pdb to epub error

[boosting1bar]

I'm new to Calibre and was having no luck converting pdfs because of the hard formatting so I found a pdb of the same book, but calibre is giving me an error on convert.

Last I heard, iSilo 3 is not a supported format and there were no plans to support it. See here.
