Never mind, I was able to fix this. In case anyone is also going through the "Your account has been closed", all I did was go to the Elysium website and go to control panel. Before entering your credentials, click on "Recover your Nostalrius Account" and follow the instructions. After receiving my password reset email (found under spam), I reset my password and was able to log back in.
These instructions may have already been posted somewhere as something to try first, but I went ahead and added it here in my post incase it can help someone.
