Midi Problem

I have always connected my Yamaha Clavinova to Cubase via a Focusrite Sapphire 6 interface. I have Cubase Elements. The midi function always worked perfectly. I have just updated to a new version of Windows and the latest version of essentials (8 I believe).
Now on a drum track I can play one drum, then have to wait 2 seconds before I can play another on the keyboard. If I try to play on a keyboard track the note goes on for ever and won’t stop.
Can anyone help please


Check, if you have the latest version of Focusrite driver, please.

Thanks Martin. The disks I have are a few years old. I’ll try downloading an up to date driver and see if that works

Martin. Just installed the driver and it appears to work. Thank you
