Hi, everyone this is my first time on here, not sure if i`m posting in right place so sorry if not.

I`m having problems with my lime wire, been using it for about four weeks now and up until today had no problems. I launched a kids programme for my children to watch that i had downloaded last week and they have watched several times before, it worked fine but then when i went to launch a different programme which has also been watched before it wouldn`t work. I then found that every video that had been downloaded what not work and video`s that i was currently downloading could not be previewed and i don`t know why. please help
