Atmega64 resetting/restarting itself?

Hi,
I recently bought a ready made component that makes some nice LED animations, it has an ATMega64 and is powered by 7 - 20V at 1 A (I'm using 12V at 1A). It was working fine when I got it, but now it just keeps on resetting/restarting itself. Im not sure why, but I get the feeling its restarting, because the beginning animation keeps repeating itself. I'm unsure what caused/causing it, as I haven't changed any part of the board, and I don't think the LED's are the issue. Any help?

Thanks.

Also, the board supports a 6 pin ISP. Is it possible for me to get an AVR programmer, and see the original C code that is on the IC?

Yes.

No, not unless you contact the author.

It is likely that you are either drawing too much power from the arduino, so you need an external power supply or that you need some supply decoupling:-
