MuseScore 1.1 not displaying score properly

I have a screen capture of a score loaded into my version of MuseScore 1.1. None of the notation is being output correctly. Any ideas? Things were working fine with 1.1 which I updated as soon as it was publicly released; however, it suddenly stopped rendering correctly a few days ago between usages.

Any help would be appreciated!

Thanks,
