Firstly, i attempted to load WoW, upon opening the small window "Launcher connecting to patch server", it would freeze and come up with an error saying Program not responding. Attempted it serveral times in hope it would work, but to no avail.

Googled to see if anyone else had problems, and seems a few people are having the same problem, but no actual evidence of advice working, yet i tried a few that people were attempting, and now i seem to be downloading 14.9gb's of WoW again... This isn't something i wanted to come home to see and have it occupy my entire internet connection for a day or two.. is there a reason i'm probably downloading the entire game again?
