I'm getting this error when I try decrypt an epub I just bought: "Error: Error -3 while decompressing: invalid code lengths set".

The script does produce an epub, but some of the XHTML files in it seem to be missing. All the pictures are there, and most of the XHTMLs, but not all.

Now it's been a while since I've used the ineptepub.pyw file to decrypt an epub, I've been busy reading up on my backlog and more than a few wonderful public domain books from MobileRead, but I know it worked for me before.

I've also tried to decrypt this under Linux (I already have the adeptkey.der file). I downloaded the PyCrypto source code, compiled and installed it. The test suite seems to run fine. But I get the same error when I try to decrypt.

Anyone got any ideas? I have a DRM-laden epub and I don't want it to be DRM-laden.
