I have no video on the downloaded file. I have only the audio. Can you help?
There must be no such problem... Just check-out you might have downloaded the Audio-Torrent... There might be no Video content in the Torrent you downloaded... Use Torrent-Searcher to get your required Torrents...
In order to fix the problem, go to Start, type dxdiag, and open the utility. Click the Display tab, check your video card model, and download and install the latest drivers from the developer's web page. After that, download and install Combined Community Codec Pack.
