Attempting to join my friend's campaign via link causes an auto redirect to app.roll20.net/editor, at which point it gets stuck on the loading screen and nothing else occurs.
I've tried directly pasting the link directly into my address bar and that makes no difference, cleared cookies and signed back in to no avail, and restarted my computer with no effect. None of the other members in the group are having the problem, and it definitely knows what campaign I'm trying to join as it comes up with the name but does not let me join.
Also unable to join my own campaign, same result.
Using firefox 13/windows xp. Chrome makes no difference. My computer has not changed since last week when it worked just fine.
Any ideas?
