Can't choose new audio outputs after soundcard change

I just switched from my trusty RME HDSPe + Multiface combo to an RME HDSPe AES. The two cards are so similar that I didn’t even have to reinstall the driver, and this has apparantly confused Wavelab. While Cubase understood that the old audio ports were gone, Wavelab did not. So, I guess that deleting my prefs MAY be a solution, but I would want to do this as a last resort only: I have so many customisations that I’ll spend hours getting in back. Are there any other solutions?

Edit: I had managed to overlook that big, green recycle symbol, also known as “Refresh”. That was it. I need some rest.
