Possible fix
I found that if you disable the Windows Live Messenger option of hiding the window border and menu bar, that it stops crashing, at least for me.
In the top right, there are the standard three icons, minimize, maximize, and close, but there's the fourth one up there that will do what you need. Click it, then at the bottom of the menu will be an item to show the menu bar. After checking that in Boot Camp, it hasn't crashed in Parallels. If you don't have boot camp, maybe use full screen or OS window rather than Coherence and see if that will let you run it long enough to make the change.
