I'm using Office 365 on Windows 7.
Suddenly I can't save changes to my Word and Excel files (I haven't checked other Office file types). When I attempt to save the file I get the following error message:
I go into the Trust Center and make everything saveworthy:
Whenever I do this I end up in the same situation as before.
At the same time this problem started Word stopped being the default program for opening Word files. Whenever I make it so via the Control Panel, it won't stay that way.
I've tried uninstalling and reinstalling Office but it has no effect.
Any suggestions?
