So i installed Source SDK for CSS editing i wanted to make a Bhop map for a server i play on and everything installed smoothly. I opened it up in the C:\Program Files (x86)\Steam\SteamApps\common\Counter-Strike Source\bin directory like i was told to. But i get this weird glitch were my 3D camera is at a sort of angle and when i moved around with my AWD keys it moves weird. I didnt do anything to the settings i just opened it and it was like this. I have a screenshot but it probably wont help.
