[Both Firestorm and the SL viewer are closing as it's loading the world. Alts can log in fine.]

I can't log in with my main avatar.  I've tried both Phoenix and the SL viewer.  The viewers just close without a message as the world is loading.  However, I can log in with an alt on both viewers.  The alt has the same home as my main avatar.

Thank you, but clearing my cache didn't work.  I couldn't find the subscriptions file, but probably because I did a clean install of the new Firestorm viewer also.

I'm also having the same problem on my laptop and desktop.  My alts can get inworld, but both viewers close when I try to.
