Quick fix using Calibre instructions:
Use the tweak epub feature to 'explode' the broken books. Find the html files (in the Oepub directory, I think) and open them with a a text editor. Copy and paste the text of the book into a new .txt file, but discard all the html code. Close all files and cancel the tweak operation. Add the new .txt file into Calibre and convert to epub. The final book format won't be very good, but should be readable, for the budget concious.
