I haven't played WoW (World of Warcraft) in about 2 years. I cannot remember my old log in, so I created a new one. (I don't even remember what email it's under). When I went to activate my games using the Game Key it says I can't use it because it's already been used (by me two years ago, lol) I sent in a redeem item, but I'm just going to call Blizzard Support tomorrow... Do you think they'll give it back to me even if I can't remember my old information?

It happened to me 3 times..
i stopped playing and went back after a year or two, had to buy 3 copies + the expansions multiple times.
I'm not from us though so i couldn't call blizzard, i hope you succeed.
