I am on my second set of disks for World Of Warcraft . I just loaded a new patch and it said there was a error it said to re-install the whole game. So i did and i am getting the same problem as with the first set. On the third loading disk it says the patch data was wrong. I have already exchanged the first set of disks because the third disk said the same thing and they told me that the third disk was defective. I had no problem with loading the second set . I have been playing world of warcraft for about 2 months and now the same problem is occuring with the new set. I don't understand why this set is doing the same thing .I really dont want to return the disks and go through the hassel again so if anyone has a answer to my problem plz help me.I'am not very computer smart.
