Hi,
I have nearly the same problem, and quite a number of others too.
I made a topic on the German Technical Support, very early this morning, haven't heard from any mod or rep yet.
There are quite a number of topics here in the English Technical Support Forum with similar problems, and there was also no official response what to do yet. :/

As you, I just want to know from a SE official, if I can just ignore that it doesn't list my Main Char and proceed...
After Error 90000 and 3102 I wouldn't want to lose the progress I made on my Main during Beta 4.
Hope we get a official statement soon...
