When importing a video file on Adobe Premiere is shows as an audio file?

WHY? Its only on my laptop that I recently downloaded… A trial version. I tried it before and it was working fine.before my laptop got re-formatted so I had a chance to re-download it today. Now though, everytime i import a video file from my Nikon D3200 (codec: avc1) it only plays as an audio file. I desperately need this to work! On my brother's laptop it works… The problem is, his trial JUST EXPIRED so i can't use that D:

Please Help ME

Added (1). I did create the video… I shot it from my own camera D:

Well this sucks. I'm broke and I desperately need this. LOL

You've both used up your one, and only, Adobe Premiere Elements 10 FREE Trial.

So now, one or both of you, have to BUY a full, legal Premiere 10, or find a decent alternative.

If you didn't create the video that only plays audio, my guess is that it is most likely Copy-protected. And, what you describe happens all the time. Try to find a non-copy protected version.

TIP: This product goes on sale quite a bit, and I bought Photoshop Elements and Premiere Elements 10 for $ 80 recently. Just check on their website frequently.
