If you don't have the sqa, or other info, then no.
Well I recently got given an account through the Scam account giveaway section. When i logged on i was amazed at the gear the lvl 80 pally had on it. But suddenly i got like 1000 tells from guildies and friends going "You got your account back?" and "You got your computer fixed already?" Well i logged off straight away and then looked at other characters. Then i just quit out of wow. But when i went on to log on again the password had been changed???? I am still logged onto his account management page but i can't change the password because the "old" password is wrong. Is there anything i can do??
