Hi, tzon89. Unfortunately I don't have Windows 8.1, so I can't advise on the dump files.
Perhaps another user who does, could help.
I DO know that Windows 8 and IE11 have given users plenty of headaches which is why I've avoided IE 11, and won't update to Windows 8.
Not much help I know, but someone else may be able to jump in with advice for you.
One of the mods might move this thread to the ID Safe forum, but a link will be left here, if they do.
