Problem with a clip i bought, Stoppes at a certian point !

[FartLove88]

I bought a clip from LMTs store, and when it reached around 3:50-4:00 the video just stoppes.
I used VLC player, and i figured out VLC player froze up. So i opened the file in KM Player, i skipped thru to the 3:50-4:00 marker, and then KM Player stopped working, it froze up as well. I needed to close the program. What does this mean ? Could it be a problem with the file ? Should i contact Suncoast Productions ?

EDIT:

The clip stoppes around 4:03, and it stoppes in VLC, MK Player and Windows Movie Player.
Its a wmv. format.

So this means its the file itself which is broken, now is there a way to fix this ?
