After compiling .gcf files from various sites, I've gotten myself a working installation of CM12.21. I have uploaded the complete index of every .gcf file needed below (on an hassle-free site :P). I've tested the beginning of each episode, and it all seems to work without a hitch. Let me know if something's awry and I'll do my best to fix it.Instructions:
1. Download the files you need.
2. Copy files to SteamApps directory.

Q: Does this fix the MountAppFilesystem() error?
A: Yes. I have every .gcf you need to run CM12.
Q: Do I need to disable Steam updates or do any tweaking to how steam handles this game?
A: No. Just copy the .gcf files into your SteamApps directory and you should be good to go.
Q: It still doesn't work!
A: Check to see if you've installed

have launched them all at least once.
Q: Thank you so much for getting this to work!
A: No problem. I love HL2 and loved CM12, and I'm glad to be of help.
