"Server Problems"

For the past week now, I've been getting "server problems" when I try and update my LJ; but I'm paid and not read-only, and I can copy+paste the entry from iJournal to the web interface just fine, it posts just fine. Any idea what that may be? I already re-logged, it's not a bad login.

[Edit: Deleting iJournal's preferences file worked; weird bug.]
