Hi everyone. I've been trying to run the source sdk, open hammer, see what happens, but whenever I try to run the source sdk from the play games list, I get this message:

MounFilesystem( 221 ) failed: SteamMountFilesystem(2428,221,0x118afbfc=,0x118afd 0c) failed with error 114: Cache needs decryption

No idea what that means, any suggestions how I can get it running?

As a side note, I put it in mapping instead of dod support as it's not actually dod I need help with.

Go on your day of defeat source/dod/ directory and edit your gameinfo.txt SteamAppId line to 300

SteamAppId 300

You might want to write a bat file like this:

@echo off
cd [drive you have steam on (ex. C:\)]
cd [insert "day of defeat source\dod" folder location here]
del GameInfo.txt
copy HammerSetup.txt GameInfo.txt

in notepad, make sure to edit what's in the brackets to what's explained in the brackets, then save to your desktop

then download HammerSetup.txt to your "day of defeat source\dod" folder...

now everytime you run the bat file it will save HammerSetup.txt as GameInfo.txt (making the 220 into 300) and make DOD work with hammer again.

It's exactly what I did.

currently I am working on making it edit the thing everytime I click on the SDK to launch it... but I suck at bat files and configs...
