SOLVED! SkyDrive - This item might not exist or is no longer available

My friend wants to share some Excel files to me, through Microsoft SkyDrive. The files are on list, but when click on them, this is the message shown:

This item might not exist or is no longer available

This item might have been deleted, expired, or you might not have permission to view it. Contact the owner of this item for more information.

SOLUTION: Save your Excel files to XLSX format and upload them again.


Similar problem likely happens to other older versions of Word files as well. In this case, my friend has saved the file in the old Excel format (XLS), which causes problems.
