Hi Darkguyver - looking for a tutor...new to p2p. playback was working with video files - windows media player played back the best so I made it my default player for limewire files. Then maybe a recent version upgrade to windows media player messed it up. Video is replaced with the screen saver, but sound runs. Tried to revert to limewire player, but cant get computer to do that...nothing happens now when I double click files. I have an option in drop down menu when I right click the file to "open with" and then I can choose limewire, but this only opens the list of limewire files and doesn't open the player. I am so frustrated!! please help!! I'm running windows xp...
