I run an AMD Athlon 64 processor. Since I started using this computer I have not been able to successfully run LimeWire. On ym old PC with a regular 32-bit Athlon XP, it ran fine. Also runs fine on my P4 and Celeron computers. I have built 2 64-bit machines for friends and it no longer runs on their computers. Is there a fix for this? Or am I just majorly missing something thats going to make me feel retarded?

Either way, even if it makes me feel dumb for missing something, please help!
