This Error everytime....?

Can anybody shed some light here. Everytime I load wavelab and press play, I get this error (see pic)

When I open Audio connections, I see this missing the right channel. When I un-install wavelab and re-install all works well until the next launch then it’s back to this. Anyhelp would be appreciated. Thanks

On some recent Macs, there is a “blank name” for the right channel. Yet, it exists. Try to select this blank channel.

You’re right and it plays fine, but that error happens everytime I hit play. Cubase shows no name as well, but it plays fine. thanks.
