When I try to upload files from my Skydrive desktop app, the (very) small files may upload, but files larger than 100Mb or so will get to a certain point and not go beyond.  If I close the desktop app, and restart it, I get the message that Skydrive is uploading xxxxMb of XX+MB, # of files remaining.  It seems to start uploading again, but always from the same point where it left off, regardless of how many times it restarts.  When I start the desktop app, I can see outgoing Byte rate and outgoing Packets for about 5 minutes, and then the upload stops.  My monitor will show that it uploaded 6-8MB, but when I shut down and restart the app, it always restarts at the same place, even after multiple restarts showing 6-8 Mb uploaded each time.
