Hey all,

I have had this problem for 2 days now. I have tried all suggested methods said in here: https://help.steampowered.com/fi/faqs/view/22C0-03D0-AE4B-04E8

Also I have tried reinstalling CS2 on top of that but I cant seem to be able to get rid of this message and play.

If you have any ideas at all how to fix this all help would be appreciated!!!!

You must have had installed something within these two days and a little prior that causes VAC to malfunction.

It can be a driver, it can be other software, it could be anything.

If you aren't sure, maybe it's time to backup your data and to reinstall Windows.
