Corrupt Zip file

I've bought a subscription at hotjoomlatemplates somewhere last year and wanted to use the hot betting template (zipfile) today. However, i get a corrupt message when I try to extract the file.
The other templates do seem to work, so what's wrong?! I've paid for it so it should work! (see attached screenshot for erro)

And can I, as an old member, upgrade from the 1.5 or 1.7 version (which I downloaded) to 2.5 for free?

Kind regards,
Bas

You probably did not download the file completely. Please re-download it.

Old members without valid membership don't have download access. Only when someone buys single template he's eligible for lifetime updates.
