As of today my Keystation 49e is no longer displaying in my Input Devices for Sib 5.1. I have tried reinstalling drivers, using a different USB port, restarting the computer, restarting Sibelius, etc.

The computer is reading the keyboard. Whenever I plug it into the computer it displays ";USB Keystation 49e"; as found hardware. Any thoughts or suggestions?

Has anybody run into the same issue? Any ideas?

I'm running XP with 2.6ghz, 1 gig ram, Sib. 5.1.

Try unplugging the keyboard, waiting a minute, then plugging it back in.

Then, in Sibelius go to Preferences>Input Devices and click the ";Find New input devices"; button.
