Hi
I have had the same problem and on Friday uninstalled an Microsoft Update (can't remember which one!). The problem was fixed. I have tried to get into my file again today (which is offline) and have the same problem. I have attached the latest Microsoft updates since Friday - which one do I uninstall and do I have to keep doing this every day?
I am using Windows 8.1 - 64 bit.
Regards
