Can't install Sonarr v 3

It came up with an epic error and said I would have to manually copy the contents of NZBDrone data folder to the Sonarr data folder seeing it did not convert it as the instructions said it would. So I copied the contents like it asked me to do. However when I start Sonarr v3 it has not imported any settings or TV show list so I now don’t know what to do.

When I used the Sonarr installer it only asked if I wanted to run as a service or not and also whether I wanted to create a desktop icon.

If v3 is now installed you can restore the DB from v2 via System: Backup, or restore it manually from the filesystem by copying the DB and config files (and renaming the DB from nzbdrone.db to sonarr.db).
