Which beta did I get access to when I bought the imperial edition of the game ?

not to beta, but to early(5 days before release) acces.

It also says beta access on my account , but that's all the info I have, no email saying Im in a closed beta. the only thing I have is it said beta access on my account along with early access .

I think that in many ways the early access IS another final beta. Consider it the dress rehearsal.

hhh will be funny if the do character wipe on the 4th

No it wouldn't lol

Under "My Purchased Games", on your main account page, if you got a beta key and participated, you will see "Beta Access." If you inputted your early access code already, it will say: "Early Access" as well. No beta's have been announced at this time.

That explains it thanks.

Your preorder grants access to the beta as well. If and when there is another beta, you will receive an invite via email, about 5 days before the event.
