Everything was working perfectly until a week ago.
But one day, i started Steam, go to my Library. And saw all of my installed games are showing as not installed. Also when i try to to install them Steam says i don't have any disk space. But i do!!
My OS: Ubuntu 14.04.2
What i tried
Uninstalling, manually removing all the data in
~/.local/share/steam and re-installing
Tried to contact Steam Support, but no response.
