Hi, Nice to meet you all.
I updated Calibre from 0.7.2 to 0.7.35 and got the message "Calibre 0.7.35.exe stopped working". It then wouldn't open. After uninstalling and re-installing several times I eventually went back to version 0.7.2. Have just tried to install version 0.7.42 and am getting the same message. Calibre will no longer open. I completely uninstalled the previous version before I started. Is it a Vista problem? - that is what my computer is running on. Thanks for your help.
