I had this problem with my cd key being in use by me for about 12-14 hours at the very start of ladder. Then a few hours ago the server went down, kicked me out when I did the nightmare baal quest. Now after waiting patiently for the server to come back up, it shows I’m using my own cd key. I waited 5 minutes to no avail. Can you guys do something or am I going to have to wait another 14 hours?
