Hey guys its just a waiting game, eventually you'll get the email to reset your password!! The reason for the error occured msg is because there are so many ppl trying to reset passwords, the emails are backing up! Just keep faith its took since last week when i updated to getting the email 2day! Hope this helps
Funny, I didn't have to wait for an email. At around 11:30pm on saturday 5/14 I tried to login just for the heck of it and managed to get the system update. After the update, I couldn't get to PSN - just got the maintanence message. 30 minutes later I tried PSN again and it let me change my password. I've been able to get online since.
