A few days ago I downloaded my second movie ever, and while it was downloading, I clicked 'Preview' and they told me that this file '.avi' is not supported, so I downloaded HyPlay and another program called .Avi and now although the download is complete, the movie will not launch!

Last month I also tried downloading my first movie and I had quite the same problem, except when the download was complete the movie DID launch, but it froze in the beginning.

Please help me, I'm willing to try to fix this problem.
Thanks in advance.
