Great to read the feedback and always useful to know what works for people to thanks for that @TheCHEWER.Hey guys! It's me again, just wanted to give you a short feedback on my problem:
I ended up downloading and installing the whole thing from ground up. I do not know why exactly these steps didn't work for me, but I figured it's because I first downloaded the Beta version from the NA server, then played on the NA server, than switched to the EU one (renaming the folder), then didn't patch the game properly on launch etc...
So in my opinion it was the best to reinstall everything, I don't want to have any similar problems in the near future
@Moonraker Thanks a LOT, buddy! Your instructions made many things clear to me, I guess I was just messing around with my files a LITTLE too much
Blood for the Pact!
