There seems to be an odd issue with this archive. Using Firefox 19 I just clicked on this download link 6 times.
https://www.ads-software.com/extend/themes/origin
Out of those 6 clicks, 3 times the download size is reported as 378kb and 3 times it was reported as 224kb.
Using Chrome, the download resulted in 3 successive corrupted .zip archives. All reported at 224kb, and all missing directories and files. A fourth attempt finally downloaded the complete archive.
IE 9 however, consistently reported the archive at 377kb across a greater number of samplings. I did not duplicate the issue using IE 9.
I have both archives currently sitting on my desktop. The smaller of the two is missing (at just a cursory glance) 2 complete directories and 15 files. I’ve duplicated this behavior more than once.
I also attempted to duplicate the discrepancy in reported archive sizes using at least a dozen other themes selected at random. I could not.
[edit] I also finally duplicated the issue using IE 9.
