Thank you for the tips. I have solved the preview problems when I follow your advice of making VLC as the default player. However I still cannot recover my lost incomplete files since they are no longer in the library because the current L/W version is the updated one, Those files are in the older version but I can find them in the incomplete folder of my 'C' local disk. Can I still redownload them by way of recovering them from the hard disk? Also I have encountered another problem whereby the L/W signal is only at one green bar and it took quite some time to start downloading more so at a very slow pace(around 10-20 kb for two or three d/l concurrently). I have done everything as suggested in the HELP section such as checking my firewall. As you know,with one bar,the search function is not working. How do I overcome this problem Grandmaster LOTR?
