"Insufiicient memory (case 4)" and "Empty input file" Errors

[hutt132]

Window 8.1 64-bit with 8GB of RAM | Python 3.4.2 64-bit | dezoomify 2014-11-18

I have all the tiles downloaded from using -s and I entered this command in CMD running as admin:
py dezoomify.py http://www.spacetelescope.org/images/heic1502a/zoomable/ output.jpg -x -vvv

I get "Insuficient memory (case 4)" a little bit after I run the command, and then a bunch of "Empty input file" errors. After it "finishes" joining the tiles the program just ends and I don't see the final output.jpg anywhere.

Here is a log of the CMD window after running for a few minutes: http://pastebin.com/5BwU78YK

Could someone please tell me what is wrong?
