If I'm downloading a film etc, in mpeg, mpg, avi, I can preview it, during the download with no problems. Once the file is downloaded (100%), I get the following message:

LimeWire has detected a corruption in the file "whatever the file name is".mpeg Do you want to continue? This is followed by the yes or no options.
If I click yes, the download completes, BUT, when I go to view a download that is, (for example) 1hr 50min in length, it will only play for 15/20 mins. It then stops, cant go any further forward.

Sorry if this discription isn't clear, but it's the best I can describe it.
Any help would be much appreciated.
