GMOD wont work, wont even start up!

Ok so i run gmod, it says loading mod in steam, then the box closes and nothing… I sit waiting… I click play to start it again and it say, you can only have 1 running, instance, whatever blah blah… so I go to task manager, close it from there and try runnning it again… nothing… its a cycle. tried deleting my client registry.blob and nothing. restarted computer and steam… nothing…

really need some help please. Thanks. x

Have you reformatted recently or gotten a new computer?

Nope, comp has been reformatted about half a year ago now… So shouldn’t have any problems…

And running well
