Newly created test Word document not syncing (though there is no error message) and ten (out of several thousand) Word and Excel files show as an error that they could not sync.

I created a new Word test document and saved it in My Documents two days ago. It is not showing in My Skydrive folder nor on my skydrive cloud. There is no error message related to that document.  I do see ten files (Word and Excel) which cannot by sync'd to my skydrive account (though I have no idea why?) but the test document is not one of those ten.  Does the fact that for some reason (?) those ten files do not sync  stop further sycns from occurring until I resolve that problem?  And how would I resolve those ten files?
