i checked in game, and your char name Zyrribiak is able to be added on my buddy list.

All this means is he exists somewhere...

as far as the account thing, i have no idea, and i don't have the access to the information you're looking for..

hopefully someone who can, will drop by and help you out.. otherwise, i don't know.. keep trying..

Make sure your account name is being entered correctly. it is the email address you used to register.

Wish i could be of more help..

EDIT: Try all of your emails. Everyone that you've used recently. double check there spelling etc..
