If none of the suggestions by anyone help, your friend may have to catch registration open again
make sure they have an email and account name written down ready (most likely better to do on notepad on the computer to save it to the desktop to remember)
ready for when they catch it to make, that way they will still know what email they signed up with C:
or if they can by any chance get into the email they signed up with get them to click the activation code if they had one or send a activation request to
[email protected] by what i know. many accounts have been glitching for the past while. they could get activated and glitch themself as "un-activated" causing it from stopping you playing either by itself or by if you attempt to log into the forums about 2-3 of my own friends have had this glitch in the past.
You might also be able to PM a mod or admin to look into this situation one of them may be able to tell you the email to the account your friend signed up with, that is of course if the account still exists for them to find
