Hello.
After I upgraded my Office to 2013, everytime I click to save a file, Excel closes without any error messages. The process keeps running, so I have to end it manually (otherwise, next time I open the file, it says it is already in use). This happens with any spreadsheet I have. When it shuts down, it creates a file randomly named (like A2512000) with 0kb.
I tried using the Repair tool available through the Control Panel with no luck. I also installed the KB2760339 hotfix.
I tried saving a new book with gibberish typed in it and it worked. If I open this same book and do small modifications, I'm still able to save it.
These errors (closing without notice) also happened with Powerpoint and Outlook, but I can't give any more details because they are rarer and I haven't noticed them happening under a certain circumstance.
Any help is appreciated, as I've spent most of my day trying to fix this. Thank you!
