New version

I've posted this problem on every conceivable forum and contact from Musescore. The latest version upload has resulted in the programme refusing to load. The main page comes up then disappears after asking if I want to revert to previous pages. My saved files will load up but I can't start any new projects. As a pro user I'm disappointed that this matter has not been dealt with in the five days since I first posted the problem. Come on guys!
