Question Upgrading from K 3.0.4 to K 3.0.5: 'Kunena Forum not found (class)'

When I upgrade from 3.04 to 3.05 I see this strange message, a red message that says 'Kunena Forum not found (class)'.
It is only shown in the backend when I install the package, it also pops up the 'installing kunena' box, but the box isn't closed after installation.
The package seems to be installed though.

Did you know that you can reinstall K 3.0.5 again (and again and again) and you will not lose anything. Did you try reinstalling K 3.0.5? Did the message appear again? Did you follow the K 3.0 Upgrade Guide ?

I do not know what this message means.

If you get the message again, it may help if you watch the video vimeo.com/69818669 ; you know what I mean?

GRIN, sorry, I just split this from my previous post

Yes, I tried installing it on top again, got the same message.

I've created a small video: screencast.com/t/tIwNaFlNeiKH
At that screen it just stays, it doesn't go any further.
