Help! Movie Download Error

[cuzchica]

I'm in the process of completing a rather large movie download and wanted to make sure that it is what I'm wanting. When clicking to view the preview, Windows Media Player is launched and I come up with this error message:

"Windows Media Player encountered an unknown error. 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'm then given the options of CLOSE or MORE INFORMATION. I might add that the more info link comes up and apologizes for not having any more info...go figure. Can anybody help me out with this or tell me what I need to do? Desperately seeking help!!
