if you are trying to logon to the site with your original account.. and can't.. clear your cache, history, etc and try again.
If that doesn't take, use email recovery.
If for some unforeseen reason that isn't working, send me PM here with your EMAIL account, the one you used to reg that old account on xs and I'll send you a personal email. You reply to that, and I'll make a new password to your liking.
If you tell me some lame story about not being able to use that email you regged with.. or that it was bogus to begin with I'll close the multiple accounts.
