I have Skydrive on two computers both running windows 7 64 bit. It has worked flawlessly since first installed until last week. I noticed that on one pc two files were out of date. Both displayed the "syncing" icon rather than the green tick. I've tried deleting the files from the local folder, unlinking skydrive, re-installilng skydrive but nothing works. This morning after the re-installed I had a message like "downloading 345mb of 350mb, 4 files left or similar. After leaving that for a while I tried unlinking and setting up again. Now all I get is "Processing Changes".
