Guys, easy way to clean register is to download CCleaner as Jackster mentioned. Instructions:

1. Uninstall cheat engine from your computer
2. Open Ccleaner. There should be an option about "Clean registry".
3. Run it, and then just delete the stuff that pop ups, there is that button "Fix these registry errors" or something
4. Now you have succesfully uninstalled cheat engine and its registry files.

I can't join either. I reinstalled the game and it worked the FIRST time, then I left and i have the same issue as CoconutCake

Please ignore this post. Sorry idk but i posted by accident

Try running cCleaner.

^ TO DO THAT
Start>Run>regedit>Click the + on My Computer if it isnt done already>Click the + on HK_CLASSES_ROOT if it isnt done already>delete the .CT folder NOT THE .CTT FOLDER! ONLY THE .CT FOLDER if it isnt there well i got no idea sorry :P

Old thread, but I'll mention that in some cases, having Cheat Engine installed affects this. If you have Cheat Engine, uninstall it and clean registry of its files

Reinstall the game.

I need help,
