I need help
So I have a boe bot. I'm programming using basic stamp and I uploaded a program. Now my thing will not let a new program on the robot. Basically I I'm stuck with my thing going straight forward and I can't change it. The computer says the thing is scanning. I did something ( idk what it was) that fixed it but it came back. Since I am a beginner it might be a rookie problem, but if anyone knows please help.
