Getting Failed to start game (app already running) when I try to launch Doom 3
I have tried everything on steam support, deleted cache, disabled firewall, reinstalled the game. I don't know what to do next
I am on Win7 64 bit, a brand new install, can anybody help?
Thanks

Did you try restarting steam?

shut down the "doom.exe" in "Processes" in Task Manager then restart the game. Worked for me

Exit out of Steam and delete the "appscache" in your Steam folder. Restart Steam. It works for me.
