moviexplayer

i have downloaded ice age 3 via torrentz.com after fully downloading it shows 695 mb or something like that but when i play it it only goes on for 20 sec and at last it shows "to play this video down load moviexplayer "
how is this possible?

For starters we don't talk about where/how we aquire movies on this site

Secondly, it's a fake file, you will not be able to play no matter what you try. You will be scammed into parting with cash & yielding no results.
