So I recently downloaded a few textbooks from amazon only to find that they are in the new .azw4 format.
I was able to strip the DRM from the books by
[Detailed DRM removal instructions removed by moderator].
Now this is where I start to have problems. If I open the files with Amazon's PC reader, the .mobi files work fine. If I import them to Calibre, and try to open them, all I get is the first two pages, or it doesn't even open.
If i try to convert the .mobi file to an epub, it does not work. Looking at the log, I get a Python Error and then a little while later a memory error.
Code:
Extracting text...

(Error Code: 1)

I was reading another thread that suggested changing the settings on conversion to not split page breaks, and to increase the "Split files larger than:" to a large number (i chose 400000), unfortunately neither of these two solutions worked.
I was wondering if anyone had any ideas as to what might be happening.
