Game Release date and Program bugs

When the game first came out for pre-sale i bought it and participated in the Beta weekend for the first time i created a character yet my e-mail address was not found when i tried to log into the game last night and i had to set up my account all over again. Did this happen to anyone else?

Why did they tell me that the game was coming out on March 6th last week when i went to go pick up the game and in october they told me it would be out February 7th. Does anyone find this anoying and why does this forum say that it will be out the 28th when the official site says it will be out the 18th

if you had problems with your account, you should contact tech support.

the official release date is listed as April 28th in the press release from Arenanet:

anything anyone else says is wrong.
