Here in lies your issue.
You where trying to upgrade from 4.8.2 to 5.02
You would need to run the upgrades to run the new version. I have ran them for you.
2 things left you need to do.
If your going to run the new vb3 enhanced features copy the templates from vb3 enhanced into the templates main folder overwriting the normal files
then chmod your config-int.php file so you can edit integration settings in admin and turn on your vb3 integration
