This is a discussion on Garrys mod problems within the PC Gaming Support forums, part of the Tech Support Forum category. Whenever I join a second server on gmod I get the hl2 exe error and sometimes when joining a server
Go to your Gmod directory (c:\program files\steam\steamapps\USER_NAME\Garrys Mod\garrysmod) and delete the folder cache. This is where all server files (lua files) are stored, sometimes two files from different servers can cause problems.
Could you also post your system specs and any tools your using with Gmod (EI, Stacker tool).
I also have this problem. Its getting really tedious to have to completely restart GMod. I'm also pretty sure it's a GMod bug as I deleted everything, redownloaded GMod and still it crashed unpon "Sending Client Info".
I'm guessing its got sumthing to do with Windows 7 as it used to work on Vista. Shame really, Windows 7 is awesome
Ah, windows 7 has a bug with Gmod not Gmod with Win7. Win 7 hates a program that uses html scripts and flash without using any IE7/IE8 plugin. The Motd screen that you get when connected to Gmod server usually has html links and/or flash animation.
This may not be the cause but its a start.
Use the file i have supplied, extract the file and place it in your Gmod directory.
The file will override the servers Motd and replaces it with a blank screen.
I have set the file properties to read-only but Win7 security is a little different so when you place it in the directory right-click the file and select properties, go to the security tab and edit each user/system account so the file is read-only for the entire system.
