TF2C doesn't apear in Steam.

As in title, I installed SourceSDK Base Multiplayer 2013 and extracted to sourcemods folder but nothing

 

It won't show up until you restart Steam

 

I always restart steam after installing mod, and this time I restarted too.

 

• Make sure you're installing it in the main steam folder's sourcemods, If you've got multiple drives setup on steam it wont work on anything but the main drive.
• Ensure you're running beta_test and that the tf2classic folder doesnt have a copy of itself inside.
• Check /steamapps/sourcemods/tf2classic/gameinfo.txt exists, if not you've installed incorrectly.

• I readed instructions and i always check this
• I checked it before
  
  P.S. First helped!
