I have left WoW 3 months ago but I decided to go back, I wanted to reinstall WoW Vanilla and BC, that worked perfectly, but when I placed Wotlk or Cata into, my DvD-rom didnt even detected that I have placed a disc in. I have tried my friend's disc. Every other CD/Dvds works only Cata and Wotlk not, Any advice?
