I also have the same problem. The only information I could find was to
recreate the Offline Files cache by holding Ctrl+Shift while clicking the
Delete Files... button in the Offline Files Tab in Folder Options. (Open My
Computer click Tools - Folder Options). However I have had the same problem
come back a day later.
