ordinal 318?
 

Keep getting this message up when trying to play a video can anyone help?

Thanks

Might be a codecs issue....
You could try to use a different media player such as the free VLC player with built-in codecs which can play almost all media files without problems. You can download it from here:

As a side note, to preview files with it you'll have to open the files directly from the Incomplete folder and not via the LW preview function.
