Hm, I didn't get a notification that you replied about this, so I'm just seeing this. 

I sent rhiannon a PM, though, I am pretty sure the problem is on your end. Even if it's not, I would hope that the zip files we download have at least minimal QC applied to them to guarantee that they are valid and for the product they are associated with. The browsers (and I've tried it with Chrome and Firefox, both result with the same problemed zips) both think the file should be smaller than what is downloaded, which sounds like the server itself is behaving incorrectly. But, if she can get me the files via another way, that's fine too. Perhaps this is happening to lots of other people but their zip program just doesn't tell them?
