I have found a way to make Gmod9 servers playable without crashing the game.

http://eevee.facewan.com/gmod9-appid.exe

Simple install it and hit patch, there will be an error so just cancel out if it askes you to direct it to gmod9. Then restart steam and when you Launch Gmod9 it will ask you to download SDK, you MUST download SDK in order for it to work.

Once ingame, type in console, sv_lan 0 and sv_reigon 0
