Of course, but it would be easier if the config-int and config-intr would be renamed into something like config-inc.php.new (like Photopost 5.5 does - vBulletin does ist simular).
It's just an idea that makes life easier

- Of course we (=the users) have to take care of our sites and in my case, i was a bit to quick

Instead of getting a backup i filled the config-files up again, missed one line and go the above error.
Thanks - both upgrades (PP & PP) are working fine for me
