To save much time and effort, the following strategies are advised if you have problems with Vista and running CSS. 1. Downgrade to Windows XP. If your computer is good enough to run Vista, it will be good enough to run XP.
2. Buy a seperate gaming computer.
3. Ask here if you think that it is not Vista that is causing the problem. (eg. Lag issues e.t.c.)
4. Finally, try typing the error message in Google and looking for results.
Thanks!
