GWCA Noob Help

I don't understand what you are supposed to do with the GWCAConstants.au3 file. Are you supposed to edit it and then save it as a .au3 file or should you save it in the same folder as Scripts?

Anyway I need someone to help me out because whenever I try to inject the game the message pops up HeroSkillFunction missing (Hooking Error)

I need help and you guys help is highly appreaciated! Hope you guys can help me out, Thanks!

GWCA project was abandoned almost 2 years ago
So looking today for someone who help u - challenge
Of course you can always do it by yourself but in my opinion better take a look into "up to date" GWA² project
For many - even better than famous GWCA
