I use a shared Skydrive of a fellow employee to access our business info, and it was working perfectly until now. 
    I Synced their "Skydrive" documents which attached to my "Favorites" as a "Sharepoint". And when there was a hang up with a couple documents     that would not sync that I could not delete off the "Upload Center". I selected the option to "Stop syncing a folder" when I did this it permanently      stopped syncing this library. So I re-synced their Skydrive, it synced successfully with the exception of one folder. Which got hung up on multiple      files. So after trying different routes to fix this, I stopped syncing that library, again. Then when I tried to re-sync it again, it began the process but    then stopped and gave me this error message, 

Error Details:
We can't synchronize this tool because of an unknown error.

And now no matter what I try to do at this point, this is what happens. I need access to my fellow employee's documents and have the ability to upload documents for her to see (i.e. a Sharepoint or "shared" skydrive). I even deleted all my previous Sharepoint and Skydrive files off my computer and uninstalled Skydrive(as a last ditch effort) and was still unsuccessful.

What can I do to fix this problem? Or is there another more or equally efficient way to share files. 
Thank you
