Problems reading PDFs and Excel files downloaded from SkyDrive on Lumia 900.

Initially a few months ago, I successfully downloaded some PDFs and Excel files to my Lumia 900 from SkyDrive and they opened and worked on the phone, then that stopped working and I now get the following messages when I try to open the files in my Lumia:

For PDFs - displays message "The document cannot be opened because it is not a valid pdf file."

For Excel files - "Excel does not recognize the file format "CD Collection" (for my Excel file with a list of my CDs)."

So the files do download to the phone, they just won't open.
Any suggestions for a remedy?

I have recently upgraded to 7.8 but that has not made any difference.
