No need to go back. But i always save a setup.exe of pinballx just incase even though Tom is great at supporting a bug fix. If you want(and i suggest you do) backup database folder and cfg folder and your settings will always be safe! i always right click on these folders and add to archive for safe keeping after i do a table update. I also use clonezilla and keep a image of complete hard drive just incase! I sure wouldn't want to start over incase of a hardware failure!
