For me it worked like this:
Search in your userprofile of your system c:\user\%username%\AppData\Local\Funcom\Conan\Pref \
and delete the folders of the account in which the chars are stored that cause problems. Start Aoc and log in.
It works for me. I guess it was the full ignorelist of my mainchar that caused timeout.
Sadly Funcom wasnt able to help with that nor did they ever response on support request.
