eeps. You sure they are all gone? LW 5.2 places them into a different location. The incomplete files are stored in a folder called Partial & is within the download folder.

As for files being deleted, that is a possibility. LW 5.2 has a strong filter to delete spam. It apparently knows certain spam hash configuration & will delete the files upon completion of downloading. That's to prevent users being affected by certain audio or video files that have viruses imbedded within them. It's also to prevent those users sharing those files back to the network without realising. http://forum.limewire.org/showthread.php?t=6391
