Waveplayer not working sometimes

vvvv beta general

at some point the waveplayer stopped working. when doing a reconnection between waveplayer and audioout the tty renderer shows:

1 day 03:01:08 : Removing node: Default DirectSound Device from filtergraph
1 day 03:01:08 ERR : A specified class is not registered in the registration database.
1 day 03:01:08 : Adding node to filtergraph: WavePlayer (DShow9)
1 day 03:01:08 ERR : This method tried to access an invalid pointer.
1 day 03:01:08 : Adding node to filtergraph: AudioOut (DShow9)
1 day 03:01:08 : Connecting from: WavePlayer (DShow9).Audio Output to: AudioOut (DShow9).Audio
1 day 03:01:08 * : nil pins can not be connected in directshow graph

what can this be?

when creating a new waveplayer the following error occurs, hmm

1 day 19:07:35 : Adding node to filtergraph: WavePlayer (DShow9)
1 day 19:07:35 ERR : This method tried to access an invalid pointer.

make sure the file WavePlayer.ax is in your vvvv\bin folder.

this is the DirectShow filter, which needs to be installed in order for the WavePlayer node to work.

sound like a good occasion to throw a clear error message :)
