Basic stamp never found on usb adapter

I just got a Basic Stamp, as part of the book "123 robot experiments for evil geniuses", and have its included PCB board built.
I have no serial port on my Gateway 7811 laptop (vista64), so I had to get a Manhattan USB to serial converter.
I have downloaded and installed the driver for the converter through their website
And I have the PCB board running on a 9v DC regulated power supply.
Now, no matter what I do/try, the Basic Stamp editor can never find the chip- Loopback and echo are YES (com 16), but no identifier.. Any Ideas? is the usb converter one of those that does not get along with Stamp, as noted in the help pages (prolific driver)? Is the "evil genius" PCB board or my assembly defective? Is 9v DC wrong? Is there something else I can do to try to get it to start up?
I have gone through all of the help page connection problems tips, and found that my advanced settings on the usb drivers inly has "disable fifo" option, no latency adjustment. Could that be the problem?
I'm really out of ideas, and so am turning to this forum. The only proof I have that this Basic Stamp works at ALL is the fact thats its little "472" chip gets hot when its on- but, besides voltage readings at the taps showing a load off the supply, thats about it.
Any help would be greatly appreciated. Thanks

Some non-Parallax serial-to-usb don't implement all of the 9-pin signal lines required by the Stamp IDE. The Parallax device works a cinch and it's inexpensive enough.
PE -- Stuff "getting hot" isn't a good thing. I don't have the circuit you reference. More info?
Loopback is a short between 9pin's 6 and 7. That's good.
If that's the case, you still need DTR on (pin 4.) [Data are on 2, 3.]

Try this.

Its fool proof
