Can't open a valid comic book

I have a valid comic book that I have been able to open on various comic readers on my computer. I also have the second issue to this particular series that I can read on my computer, and that Ubiquity has picked up and displays the pages just fine. However, the first issue of this series is just not working. I have re-downloaded the comic, I have uncompressed and renamed the pages (001, 002, etc.) and recompressed it. Nonetheless, it will not open this book and I can't figure out why. Here is the stack trace:

I would be happy to send the file to anyone willing to help me troubleshoot this issue (no pun intended).
