MountAppFileSystem() failed: ... Bad launch configuration

MountAppFileSystem() failed: SteamMountAppFilesystem(0x12e0f4) failed with error 4: Bad launch configuration

I just updated the entire suite, reset game configs, Refreshed SDK contents, ran HL2, HL2DM and CS and then exited, then ran Hammer and tried to run the map I've been working on for so long and ... GGGGGAAAAAAAAHHHHHH WTF! Anyone run into this after updating and figured out the fix yet? Everything is set to HL2DM for the game config. I notice that Hammer now uses (and REFUSES to use anything else!) environment variables for the paths to the various folders. I tried to manually put the absolute paths in there, like I had before, and it just resets to using the variables, though those variables should resolve to the exact same place, however I assume Steam has taken care of creating those variables for me. If that's not the case perhaps this is the issue. If so, can I just slap together an environment variable using the absolute path up to and including the user ID. For instance, it has $SteamUserDir\half-life 2 deathmatch. Should I go create a variable that makes $SteamUserDir = D:\Games\Steam\SteamApps\MyUserID\ ?

I did a search on goog for this error and the closest (in ENGLISH) that I came across seemed to be a bunch of jerk-offs that don't actually own the game but instead are doing something "else". Well, I'm staring at my HL2 box right now wanting to smash someones face in.

All I can tell u is that I had the same problem so I backed up my map and reinstalled the sdk.

I had this problem too a while ago, unfortunately reinstalling the SDK was the only way to fix it :sad: If you do and it still doesn't work, try deleting the GCFs and the directory yourself manually.

I tried to preempt as many potential problems as possible by thoroughly reading the update web site and all information about the release including the faq and all that jazz prior to allowing the update so I was a bit surprised when this error happened, however the one thing I hadn't tried yet was a nice cold boot, prior to taking drastic [next] step of blowing it all away with a reinstall. Things have squared away.
