Long story short, after you already get your ban to be lifted from your account or reactivate an old account, you will get a password reset e-mail containing one time login and change your password immediately.
However, on one particular account that I just restored today, the one time login link lead me to "access denied" page.
The account itself is already restored, but my problem is that it seems the one time replacement link in the e-mail above does not work. Therefore, I can't access the restored account.
Any tips or help how to send ticket on this issue if the link above doesn't work despite the fact the account is now active / not banned?
