Musescore 2.0.2 "has stopped working"

I worked on Musescore 2.0.2 yesterday with no problem. Today the intial title page comes up and within seconds the message "Musescore has stopped working" appears and a Windows message "there is a problem.... etc." Is there a problem with the website?

I've used MS 1.3 to contact the forum. My OS is Windows 7.

Many thanks
