Help with a "Babylon 5" model?

So I was digging around the Tubes of the Internets and came across this:
babylon 5 -

I attempted to download the Warlock-class destroyer model and did so, but when I went to open it (with iZip, which I all I have on my iPad) it wouldn't open. It says it is a file that's not supported by iZip.

Anybody have any ideas, or already have copies of the model they could email me?

Thanks.
