I've gotten this error message a few times now, and it seems to be the case almost always when I open an Excel file that was originally attached here as a zip file. I've tried opening from Excel, from opening Documents and navigating to the file, and both with and without extracting the file. This doesn't happen when I open start Excel or use other files. Is there a way to fix this?

Also, I tried using the Search here and got a memory allocation error a couple times and then a blank screen a couple other times.

Thanks.
