Hi
1. Did you delete the underlying folders before opening the DLP?
2. After deleting the folders, when you sign into the DLP, is the notification 'i' flashing/highlighted?
The reason i ask is that my understanding of the download queue, is that all items in your queue should be checked (and download attempted) at the same time and if they fail they get marked as such and won't get tried again. I know that it isn't possible for an end user to clear their own queue, but i don't know if that is even possible.
