There was a Proseries Alert March 18th that they were aware that the program would crash randomly. Caused by an update. 

Apparently they have not fixed the problem yet. I have Proseries and it crashes multiple times a day. For now I've just learned to save every few clicks - very annoying, There are multiple system problems this year. More than normal. From what I can see, Proseries has made no attempt to correct any of them. Even though they've been brought to their attention.
