Hello!
So I deleted the cache folder inside WOW folder today, nothing else, nothing less.
That resulted in a great PITA however.
Now when I open the launcher it started downloading the whole game content again although I have all data in it's place and unchanged.
Searching Google I found 1 topic in blizz forums about this particular matter and it was not solved so that's why I decided to turn to
this, more intelligent environment. Hopefully somebody has a clue what I'm jamming about.
Thanks to whomever finds time to leave a reply!
S.
