Crossbar configure not opening !?

Hello,

my Configure Crossbar settings dont open. How can i fix this ?

I have the same problem. Just installed OBS with the USB Videograbber by Gembird. I would like to use de S-VHS option but I cannot switch to that mode because nothing happens when I click on 'crossbar instellen'...
Besides that, I don't have any sound, but that's another problem....

Those functions are provided by the drivers for the device, not by obs. If obs doesn't pop a window up, that means the driver doesn't offer it.
