I've uploaded a new version with the fix included, so once ModDB clears it everyone should be able to play without problems. For those who don't want to wait, the manual solution is to just replace the text in gameinfo.txt.
The file gameinfo.txt should be in the top level of the mod folder. For me it's in "C:\Program Files (x86)\Steam\SteamApps\SourceMods\anti-citizen". If you want to update this way, just make sure to back up your old gameinfo.txt. You probably won't need it anymore, but it never hurts to hang on to backups.
Below is the text you need to fix the game with Steampipe. Just paste it right over the old text and save the file (and don't forget to back up the original just in case).
