To both of you;
Have you clicked "Refresh" when you looked into the Library window? "Refresh" button updates the shared state of the files and folders.

Andy, I suspect if your problem is related to the matter we're dealing with in this thread. We are here dealing with 'upload' issue, whereas yours has to do with downloading and completing.

I am pretty sure there were couple more threads in the past which specifically dealt with your problem. Why don't you take a look at them and see if they'll provide you with answers.

Good luck.
