You are welcome. 
Tough to say… maybe a recent computer OS update? You don’t list it but, I assume you are running Windows. If Win 10 then we all know there have been a lot of updates that just might change settings and break things like you described.
Probably would be a good idea to check if you have the latest Yamaha/Steinberg driver installed. Maybe that would fix a few things too.
Regardless… I’m glad you got it running again.
