If you are still experiencing problems from the account migration, a few issues have been addressed, or are in the works to be addressed, according to the UO Herald:
Hello everyone,
We wanted to give you guys a quick update on a few topics. The issue with Accounts being stuck in a Trial state has been fixed. If you are still experiencing this problem please contact our Customer Service by placing an in-game petition. Housing is still in a no decay state till we finalize the testing, we hope to have this finished along with re-enabling Veteran Rewards by the end of next week. We’ll keep you guys updated when we have additional information to pass along.
Thanks everyone!
The UO Team
