After having many problems with downloading the patch I managed to succesfully download it after 6 hours or so. Afterwards when I try to login I got another error: battle.net error # 107. ''There was a problem logging on with this account. You may not have a World of Warcraft game attached to your account, or you may be logging into region different from the one you made the account in. If you continue having trouble, please contact Customer Support.'' I searched on the support article how I can solve this, but I am on a English client and my launcher says the game is fully up to date.
Error 107 occurs when no game accounts have been found on your Battle.net account.
Usually this is because your client is attempting to log into the US servers instead of the EU ones.
Please go to your World of Warcraft WTF folder, and open the config.wtf file with a text editor. Here, add or edit the Locale line to read as follows:
SET locale "enGB"
Save and exit the file, then try the game again, and let us know what happens.
Thank you very much, i never thought i would find a solution for this. Before i changed config.wtf file it said ESRB when i was going to login. Now it says PEGI in the left bottom corner. I'm from Sweden so i was of course wondering why it said ESRB.
Thanks again for the help ;) And good luck to all folks out there with these problems!
