Likewise...my groups list in the chat window shows only the "none" option. My group tag remains over my avatar, but I can't access any of the group chats, including the one for the group showing its tag. My profile, however, lists ALL the groups I am in.
I've tried clearing the group cache and restarting the application several times, with no luck. I run two groups, and will not be able to administer these groups until this is corrected. Help!
Oh--I have one other alt character and haven't had any problems with it.
