Hi
Apologies for not getting back to you sooner.
We do not use sharepoint and so I cannot be sure what is happening. However, there is a problem similar to this with zip files.
Zip files can be opened a if they are folders. However, the files inside are not proper files - they are part of the single zip file, and hence file references do not work.
Try extracting just one or two of the files from Sharepoint and pop them on your hard disk and then try again.
Hope this helps.
Regards
Jenny Hayes
