I keep getting a messagebox on startup talking about getmaps.lua. The error seems to be why I am unable to play singleplayer with this dll. Deleting the old files I installed from code_lua, verifying integrity of game cache, then reinstalling this dll hasn't fixed this.

I went through each and every folder from inside code_lua and deleted everything that gets modified by it, such as the Awesomium dll and the various changes to the main menu, then verified integrity of game cache. The issue still occurs after a fresh install of code_lua. Am I doing something wrong?
