The Grand SE3 doesn't fully load piano, freezes Cubase

The pianos usually take about ten to fifteen seconds to load, but this is an occasional problem where a piano loads most of the way, then permanently stops loading. The rest of Cubase still functions when this happens, but it will freeze if I try to do anything that affects The Grand 3, such as remove the track it’s on or try to load it onto a new instrument track. Cubase must then be shut down via Windows Task Manager.

Steinberg support instructed me to update my eLicenser, uninstall The Grand 3 and The Grand 3 SE, and then do a fresh download and install of The Grand 3.1.1. I did all that, but I’m still occasionally running into the same problem. Steinberg’s last piece of advice was to reinstall Windows, but, since The Grand is the only VST giving me problems, a Windows reinstall is obviously not going to happen.
