Apperantly some AO players have recieved spoof emails about their accounts. Mails state that unles info is updated, you won't be able to play after 48h. Of course it includes fake link to registry page.
IF you recieved any email from Funcom, in which they are asking you for any info, delete it.
If you have already followed link and updated info on spoof page, I would recomend to go to real FC registry page asap and change password ( you can get link to real page from official forums).
