Sorry cant really help at the moment but i can suggest going to the prev version and using that, v1.0 has changed the default header file from WProgram.h to Arduino.h, maybe that has something to do with it, iv found a few strange thing myself in 1.0 and also dont worry about using R3's in the older versions, as they work fine for me, just make sure you point to the driver folder in 1.0 for windows to install it, then go back to using the previous one.
