Alright, just had a chance to try everything with gzip disabled and still no luck.

I've enclosed all the files (other than the images) that your package contains, from my webhost.
My host is running PHP 4.4.7 with Zend 1.3. If you need any other server info, I can supply that if it would help. For some reason I'm beginning to think it might be some setting my host has setup that's causing the altercation. I'm not extremely savvy on all of that though.
Sorry for all this trouble. =/ This is an awesome addon though.
