Some problems with conversions

[babychaos]

Am a little new to converting epub files to mobi. Most of my 60 or so books have worked fine, but there are a couple of them failing for some reason. The error message i get below. Can anyone make sense of it?

If I am getting this figured out
You have a malformed part1 file.
Use Tweak (tap T with the book selected and expand. Open part1 with notepad..) Line 2

BTW, it would not hurt to validate EPUB's with Flightcrew

It's impossible to help without access to the books. Open a ticket and attach the files that are failing to convert.
