Motor library & driver compatibility

I am trying to use the Adafruit motor library with my Arduino Mega and the Adafruit motor shield. From what I know, I think the library is only compatible with older versions of the Arduino software. However, I have tried using version 1.0, and that didn't work. I have already installed the newer drivers for the Arduino, and that seems to be the problem. Is there a way that I can reset the drivers so that I can install an older one from the 1.0 release? Thanks.

The Adafruit Library is also written for the Arduino Mega. Why would it not be compatible ? In the source code the code is adapted for version 1.00 and above. So it should work with the newest 1.0.3.

Do you have a Arduino Uno ? Perhaps you could try that.
