Not sure if it has anything to do with the server update, but I logged out for the update today, and I can't log back in even though all worlds are now available. When I try to enter a world I get an error message that reads:

Cannot continue because en-GB/LOTRO_Eula cannot be located.

I've uninstalled a few times and reinstalled (the instant-play version), but the error still occurs. Any suggestions?
