Well when trying to run any tool in sourcesdk with a orangebox game I get the error “Can’t force single thread inside a thread”. But using Half Life EP1 it works fine. I kinda find it odd because at one time it was working.
Do you have any game from the orangebox?
Yes Portal and EP2.
Try and manually rebuild the Ep2 game configuration.
If you have a game running then restart it after you open hammer.
Well I decided to add Gmod to the EP1 conflagration and it would not load maps. so just for the lulz I tried to use the ep2 configuration one more time and it worked… go figure
Well thanks for the help guys. I will go back to lurking now
