I cant play any of the movies viedos clips etc. etc. Ive downloaded. why is this?

What player are you using? Try VLC player, it's free & has codecs installed... plays most things You can download it from the link below

i did but it still doesnt play. i have windows media paly nero and abunch of others. the files a mpg and dont play i double click, right click luanch etc. etc. and nothing happens

With VLC, you'll have to launch from outside of LW. Go to your LW library, click on Saved Files then Explore. Your saved folder will open, try to play from here & see what happens.

Is this happening with all video files? Are you checking the files with Bitzi before download?
How to use Bitzi

got it! thanks!

I had the same problem with VLC player as Seahawk--the fix worked-But now I can't preview any of my downloads;is there a way to get both features to work .

You'll have to preview by opening the incomplete folder outside of LW too
