Cannot convert one of my PDB eBooks

[solitaire]

This issue is specific to one particular title only. It is a non-DRM ebook, purchased directly from the author's site. I can open the PDB format without having to enter any credentials on my PC and WinMo device.

I cannot open it on the nook since it asks for credentials and there are none associated with this book. This is a known issue with nook. The only way around it is to convert it into a pdf or ePub format. Hence the need for conversion.

I have managed to convert other such books successfully, so this issue is with this particular title.

I understand it is not a Calibre problem, but any help would be appreciated.

I recant my statement above that "this is not a calibre issue". It is as I was able to convert this PDB successfully after downgrading to Calibre V0.6.35.

I have posted this in the actual thread for such issues and I would request the moderators or admins to merge this thread to the original one or close this as this is has been identified and resolved.
