I have recently tried to install patch 5.1.0 and it says it is installed however every time i log into wow it says "please install the patch and restart world of warcraft". Yet when i click the restart it says the game is up to date. I first thought it may be due to my mac however i have collaborated with a few PC friends and they are experiencing the same problem. I have scanned the threads and tried various solutions including deleting Battle.Net file, Reconfiguring exe files etc etc. Wondered if this was indeed a universal problem? and if so has anyone figured out how to fix it? or if blizzard will be doing so anytime soon?
