i actually have no idea my computer got fried a month ago and i recently aquired a new system with an AMD64 and I'm still waiting ot get it running on ecm-gmp. I don't remember how to get it running though. I don't even have the program and i don't remember how to get .tar file to work. I haven't really played much with any computers since i starte the thing running a few months ago. I'm more of a point and click kind of guy. Some help though and i would be back on track in no time.
