Hi,
I think I've deleted the *app file that runs CDpedia.
Is there any way to recover the file or should I unistall the SW and installed it again?
Lost the *.app file
You can always find the latest CDpedia.app file on our website for download. Your data is not kept with the application it is kept inside your home folder at ~/Library/Application Support/CDpedia. This is the folder you have to backup and not delete as this contains all your CD information and covers.
