Ok so I had a look at Lime wire and my files.....I'll explain it all from scratch.....
I click on the library tab then underneath saved files top left hand corner I usually click on video then my download list appear in the window but this time nothing comes up in any of the tabs only incomplete files and saved files then it says the specified file could not launch due to security reasons and then I push the explore button to open the shared folder and i right click on the episode to play it in windows media player and it opens it but says that file was corrupt during transfer even the ones that i had already downloaded from few days ago that i have watched and they worked perfectly fine.......u mentiond the avi to exe thing well when i go into library at the end of each title it has episode blah blah.avi and then when u look across to type it says exe........so i have no idea wats going on??????
