I'm having the same problem. I didn't d/c or anything, I just can't log back in to either characters even after clicking register IP. It says "unable to log in" after clicking a character.
It literally says "unable to log in"? I've never heard of that error before... If you guys could please reply with the exact error message you are receiving and let me know what one of you character names are please...
My IGN is Reeves, however I'm from Singapore and as a result I have a dynamic IP which changes every time i log on. That said, I was still unable to log in for the first time despite having resgistered my IP
