Themeroller ZIP broken

Themeroller ZIP broken

I've tried to download a custom theme using Chrome and Safari on Mac and the ZIP appears to be incomplete or corrupt.

When I attempt to unzip the downloaded ZIP, I get the following msg:

End-of-central-directory signature not found.  Either this file is not   a zipfile, or it constitutes one disk of a multi-part archive.  

The download seems to just sit there at the end for several seconds and then finally "finishes" at the same size it was during the hanging portion, leading me to believe the end of ZIP is not completing.

Anyone else having issues?  Any ideas?

Here is the theme url if it matters:
