First thing I would try is to uninstall/install the full (new) version.
(paying attention to the licence issue if you have a MAC).
I would always back-up my league data each time I update as well.
(although uninstall/install will not delete these...it's better to be safe.....)
Patches are OK if they work. But I have more faith in the full files if
something is going screwy.
Try this and let us know.
