Sometimes when DLing from Bestanime the clip will 
nto download fully, so it will be halfway done 
but say that it is complete. The only thing I can 
suggest is a) try DLing again. If that does not 
work, you have two options.

I have the whole video. I can make you 
screencaps, if you'd like.

Or I know other places where you can DL it, and I 
would link them here, but I'd have to go through 
my fav places folder, which is massive ^^ If you 
need me to, I'd be more than willing, but right 
now I'm just not in the mood to brave a search of 
my links...

Anywhoo, hope this helps!

Ja!
