It works! I have a fix for the "The application has failed to initialize because the library bink32w.dll was not found" error or something like that. Install MW2 (If you have the disc, use that), then go to the C:\Program Files\Steam\steamapps\common\call of duty modern warfare 2 folder, then copy the "zone" folder and the bink32w.dll file from that, then put it in your zero gear/server folder. A box should come up asking if you want to replace the Zone folder that's already in that directory. Press yes. If this is the first time you're using the Zero Gear method, you will have to edit a file. Edit the Zero Gear.bat file in the main ZG folder so it says:
THEN start Zero Gear Demo from the Steam Games List, and you should be playing again.
cd c:\program files\steam\steamapps\zero gear\server
But thanks a lot Godly. This beats my tutorial by a mile! And you forgot to include the bink32w.dll file in the RAR archive, but it's a nice tutorial anyway.
