This game is currently unavaible?

I’ve tried everything short of uninstalling, but nothing is working to get it fixed.

I’ve already tried everything in http://supportwiki.steampowered.com/wiki/Steam_Error:_This_game_is_currently_unavailable

Nothing appears to be working.

me and my bro had the same issue. go into task manager and under processes look and see if hl2 is running. if it is end it. then try and start gmod. hope this works

This has persisted through multiple computer restarts, and checking right now, nada.
