You are using the test DLLs I linked to in the repository aren't you? Let's see... right next to the link...I get the same message if I delete my database... I use Mediaportal 1.0 RC3 and moving pictures r328. Any ideas of what to do to make the plugin work again?
And btw, thanks for the best mediaportal plugin so far
If you are not a developer, download at your own risk!!!
