Level 40 Ring Quest.

Hello. I appear to have a problem as a dual blade; Cassandra does not have the quest for the ring anymore. After I got the armour, it said there was an unknown error, and I was unable to continue. Should I just stay at level 39 until there is another server check, or is it likely that it will continue to the Hard fought level 50?

Edit: So dual bladers can't get the rings?
