Alright, thank you for the advice SWAT. But I play at school because my teacher gave me admin so that I could help out with the school network, so I've already installed CS somewhere else and that didn't fix it... I used to be able to get into servers that had VAC on it every now and then...even when I couldn't get into it though, it still would start to "download/precache resources" and do the little bar...but now as soon as I double click on a server that's VAC secured it just says I'm banned. And I highly doubt it is possible that someone could have figured out A)steam account on the school computers, B)gotten my password, c)Downloaded hacks onto the school computers. I believe this because I set up a key string in the registry keys of the computers, that deletes the account names of the people that have been on Steam and wipes out anything that was downloaded in Steam. Plus I have it so that things can only be put onto computers through the Server Admin account, which no other students know the password to.
