won't fix issues during preflight

I am trying to do a preflight for a word doc without images, so no layers. It runs the preflight, says it's fixing issues, but when completed said it didn't flatten layers and it isn't a useable pfd-x file.  If I bring it in as a word doc, it won't convert it to a pdf. I get an unexpected error notification. I convert to a pdf in word and bring that in and then do the preflight, which is fails.  I click the analyze and fix button. I have been having nothing but issues with adobe reader for the past 6 months. The file has no images, I don't think it has any layers. If it does, I have no idea where they are. I keep getting a your file has layers that need to be fixed.

Got any suggestions?
