Sorry to hear you are having trouble.
Is there a specific action, or actions, that result in a crash?
I've also noticed that shortly before the crash all the tiles on the currently visible page are displayed with almost no height so they are all compressed at the top of the page, apart from any 'live' tiles that represent open apps, which appear as normal minature windows.
Is it possible to get a video / screenshot of that posted here?
