Hi, Condition Zero doesn't work anymore on my Windows Vista 64-bit OS. I played CS on the same laptop awhile back and it worked fine but now after reinstalling it I can't seem to play it. When run normally I would get "Available memory less than 15MB! " I have found that CS needs to run in Compatibility mode in order for it to work but when run Windows XP(Service Pack 2) Compatibility mode, I would get the Loading screen and it would remain like that for hours. And when I open the task manager it would show that the program is not responding. I have searched over the internet bu can't seem to find a solution for my problem. Please help me out. Thanks.
