[Kumiho]

Well on 7/9/2014 around 5:30 i was playing on a beta server for Cactus Canyon and then i start to lag a little then the next thing that i know is i am Vac Banned from TF2. I tried rejoining and joing on different servers but i got the same message...
Message:

Just wait.

I had the same problem and I fixed it by doing this:

In the command prompt, type the following command and press Enter:
bcdedit.exe /deletevalue nx
Restart your computer. Launch Steam and test the issue again.
