I'm trying to get into the Dungeons and dragons online game but the account part isn't working. I did everything right but it keeps on saying my username and passwords particularly isn't correct. Anyone ran into this problem as well? Any help would be appreciated.

Are you VIP? Free account? My conspiracy theory is that when their servers are overcrowded, they kick free account players first, and bar them from reenterring until the servers cooled down. I had this issue quite frequently when I was a free account, then I went premium and this never happened to me anymore.
