Need some help with Jon Macs SD card program update method

I am trying to use Jon Mac's code (which I think is pretty neat btw)-
I have Version 1 of my code running in the Prop which includes the above method. I have made quite a few changes to my code so now I have Version 2.
Here's what is happening:
1. I use F11 to load Version 1 into Prop. Works fine. Looks for the update.pgm file to see if present. Reports card mounted but file not present. All is good. Program runs.
2. For testing I use F8 and then "Save EEPROM file" and save Version 1 to a file on the SD card named update.pgm. I insert the SD card into the Prop board and restart. Program mounts SD card and finds the update.pgm file, copies data to EEPROM, restarts and Version 1 still runs as expected, reported as SD mounted but no file present (it erases the file after loading eeprom) so continues on ok.
3. Ok now on to trying an actual update. With Version 1 still running ok on the Prop I use F8 and the procedure mentioned above to load the EEPROM image of Version 2 named update.pgm onto the SD card. Insert the SD card into the Prop board and restart. Boots up as normal using Version 1, mounts SD card and finds file named update.pgm. It proceeds to copy data to eeprom and when finished it restarts. Prop is bricked and does not start up.
4. So next I load Version 2 onto the Prop using F11 and it comes up working with Version 2 as expected, checks SD card for update file (none found), etc and runs ok. Again using the F8 "Save EEPROM file" I save Version 2 as update.pgm to the SD card. I insert the card into Prop board and restart. It goes through the steps of mounting card, finds file, copies data to eeprom and restarts. Comes up working fine as Version 2.
I don't understand why it doesn't update Version 1 to Version 2 and run. Any ideas? Sorry I can't post all the code as it is part of a large project I can't reveal. I can tell you that the Main object is exactly the same on Version 1 and Version 2. The first thing it does is start FDS serial, pause and send the message to PST of "Booting..." It does not even do that after trying to update with SD card from Version 1 to Version 2.
As I said earlier there are additional objects, some code and variables added in Version 2 that are not in Version 1 but the start up and message are exactly the same in Version 1 and Version 2.

Comments
That code is a little dated, but I have deployed it in a couple products and NEVER had a problem with it.
Since you can't reveal your double-super-extra TOP SECRET project, I suggest you write an test app that fails in the same what that we can see where you're going wrong. Paraphrasing Tom Cruise in Jerry Maguire, help the forums membership help you.

Both pieces of code are exactly the same with these exceptions- Version 2 has 2 more objects and there is a couple variances in verbiage in the DAT section otherwise strings are same size.
Since playing with this some more I noticed if I comment out the 2 additional objects in Version 2 that are not present in Version 1 then the Prop will boot up again after I update via SD card but the code did not get updated. Still shows Version 1 after PST indicates that the process is done. So I think the main problem is the EEPROM is not getting updated for some reason.
My board uses a Microchip 25LC512-E/ST EEPROM.
Any help with this greatly appreciated.
Thanks.

This line was the problem:
I replaced it with this line from his demo program:
Seems to be working now but will do further testing.
Jon- you mentioned that this was some outdated code. Any updates or enhancements?
Thanks. Marking solved for now.
Excuse me while I put on my shocked face....
And I said the code was a little dated, not outdated. It works.
I apologize to everyone that I'm not as sharp a programmer as many here but some things aren't apparent to me at first. I'm sure it appears as though I'm just asking for someone to write code. If you only knew how much I go through and write myself before asking for help. This has been a continual learning experience for me the last number of years as I'm sure it will always continue to be.
For the most part the forum has always felt like a welcome environment but lately there seems to be an angry undertone to some replies. It's like walking on egg shells to make sure you don't ask the "wrong question" or try to phrase the question in the wrong manner.
