Whenever i try to preview or watch a fully downloaded video clip, windows media player shows the following error:

Windows Media Player cannot play the file. This can occur when another program or operating system component encounters a problem but does not communicate the nature of the problem to the Player.

I am running the latest version of Limewire - and using WMP v.11

Can anyone resolve this? It was working fine - and for some reason this has started to happen!!!

Thanks
