Starting yesterday there was a steam update on all the source games And verifying all steam files. This caused many problems
Solution - this might not work for everyone!
Go and search the entire c:/windows/ folder for the following files "steam.dll" and "filesystem_steam"
And delete them.
Make sure that you don't have programs or files that interfere with steam
if the above dont work just wait for the update from garry he will do the following when he gets up:
Time: Get up, noticed a steam updated
Time: Realised gmod is fucked, Need to recompile with the new update
Time: Hit a snag in the compile, need to rethink this through with coffee.
Time: The update has compiled.
Time: Sent the update to valve, Just up to them now.
here is a message from garry himself that he will address issue:

Last night’s Source engine update has broken Garry’s Mod. I say this every time – but don’t be mad at Valve about this. This is just the price we’re paying for being on the latest and greatest version of the Source engine. The alternative is to be stuck on an older version of the engine – which I don’t think anyone wants.
I’m looking into making an update and hope to have it out as soon as possible. This has hit a bit of a roadblock though because I can’t get my hands no the up to date interfaces from Valve at the moment. I will edit updates into this post as and when I have them. Maybe play TF2 for a few hours to fill the time?
