--- Comment #6 from Rosanne DiMesio dimesio@earthlink.net --- A fresh wineprefix is one where nothing has been installed yet, so if your second backtrace is from the same wineprefix you were using before, it's not fresh. Either delete it or (if you have other apps installed there that you want to keep) install Kindle for PC to a separate, 32 bit wineprefix. http://wiki.winehq.org/FAQ#wineprefix
