So I've checked our logs and it definitely automatically banned your account for aimbot detection. It's very rarely wrong. I'm willing to give you a second chance since your SteamID looks clean, but if I were you I'd make sure whatever happened with your graphic card won't happen again.
If SMAC detects you again for aimbotting (with such eye tests violations), I'm afraid the ban will have to stick. we see this detection frequently, and you can check our Sourcebans page, all the SteamIDs banned are known hackers. Is that fair?
I've removed the ban on your SteamID, you should be able to connect again.
If you have any questions, feel free to PM privately.
