Error when converting from mobi to epub

[daveldhu]

Hi, sorry if this question has already been asked but here's my problem.

I'm trying to convert a Kindle ebook to an epub. I used mobidedrm to convert the .azw to a .mobi, and then I try to use Calibre to convert from mobi to epub. This process worked fine for all but 2 books, which give me an error, the output is:

ERROR: Conversion Error: <b>Failed</b>: Convert book 1 of 1 (Eclipse)

I'm new to this so it may be something obvious, but any help would be appreciated.

Thanks!

That error typically means the files have been damaged, usually during dedrming (basically the error sayas there are inapprpriate bits of data in the file that are preventing ti from being parsed).
