Gmod closes upon joining a server.

No error, no hl2 has stopped working… just closes and goes to desk top. Was working fine until several minutes ago.

Any ideas of how to fix this?

I run a server and this happened to about 30% of the people who joined. Try other servers, If you Garry’s Mod all sudden STOPS it’s because of ‘Steam auth ticket has been canceled’. I don’t know how to resolve this but hopefully that gets a bit closer to a solution.

Solved. Verified game cache and uninstalled excess addons, I can join and play on the server now.

Thanks for your help.

Well fuck, it keeps happening now.

Anyone have any ideas? I have tried verifying and defragmenting.
