i have recently updated to the last elicenser version. Still unable to open cubase. I’m using windows 10, doesnt seem to be the issue here. Anyboy having the same problem ?

Thanks for your time

Hi and welcome,

Try to reinstall your Yamaha/Steinberg driver, please.

Same problem here after recent wind10 update.
