I'm running an AMD Athlon 1.2GHZ, Geforce2, ME, 384 RAM, and I have that same freeze up problem except I dont get that loop message it just freezes. I used to play it when I had 128 megs of RAM but then I installed 256megs more cause it went to slow and now when I play it locks up after like 5 minutes or less of playing and I also have to restart. I dont know what the problem is I need help as well. And my pc CAN handle the extra RAM too.
