Angry Robot book conversion problem

[Gunner54]

I downloaded a book from Angry Robot (an ebook that strangely arrived as a .cbz file). But when I tried to convert it to Kindle via Calibre it was a no go:

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

Any ideas (ive tried renaming the file as ePub)?

Thanks in advance.

that error indicates your cbz has no images in it. You need to contact angry robot.

After several more attempts and miss-fires, i have solved the problem. When downloding from Angry Robot I discovered my system was changing the files to a 'zip' which was causing the problem. So when i made the final attempt i chose to open the file and not to download/save as a zip, End of problem!

I dont believer Angry Robot adds drm to their books, in fact they mention Calibre as a program to convert them. I salute the companies that do not use drm, but i understand why some do - and i do not agree with disabling it without permission.

Yep - we've discovered that (for some reason) some systems are either renaming the files as a .zip, or removing the extension altogether. It's something we're looking into. And yes - all of the eBooks bought from our online store are DRM-free.

Thanks for the purchase, and I hope (now you can open the file) you enjoy it!
