I built my new comp for X-Mas. Here are the specs...
AMD Athlon XP 2100+
512 megs of DDR Ram
128 meg DDR ATI Radeon 8500 LE Vid card
Sound Blaster Live sound card
Windows XP Pro with Sevice pack one

I install the game and it fully installs. Then when I try to upgrade to 1.11 or 1.10, it says that there is not a UK or US version on my ocmputer. Anyone know how to fix this or know what is wrong? I want to play this game soo badly. Its been forever since I have played. SOMEONE HELP!
