Cant join a server

Hey umm i just updated my gmod and i was building something in SP,i finished and tryed to join a server i got this

Disconnect: This Steam account is being used in another location

WTF?Dunno if its a gmod problem or steam problem…I changed my pass,but it still aint working

It means your little brother Timmy found your password.

That or you somehow logged in twice… Have you tried to restart your PC yet?

Rename clientregistry.blob to clientregistry.blob.bak

no if someone found out my pass it would kick me off steam but it didnt…
