My iPad II email app crashed today while trying to forward a very large (11 gb) file. Now it won't restart. Just gives me a blank page with the utility icons in the upper right corner for about 15 seconds, then closes back to the home screen. I have a large number of folders in that program holding files I need to hang onto and don't want to loose them. They are probably backed up, but the hassle of restoring everything is something I really don't have a lot of time for right now. Any way to recover this that anyone knows of. I did do a restart, but that made no difference. Running OS v8.4 right now.
