It's a cbz and it works perfectly well on my computer. I'll try again today, but if it doesn't work I may need a crash course in how to do it via the ftp (it's been awhile).
(Edit): Well, it's still not working. I wonder if it has something to do with the Catchpha (or however you spell it) box at the bottom. There was no code visible, so I didn't fill anything in.
At any rate, if someone could PM me the ftp info, I'll post it there. Thanks.
