I’m running 7 on a dual core PC. After a new project grows just a bit, Halion Sonic SE won’t allow me to load new instruments. The load progress bar gets to half way and stops. Once this happens Cubase seems to get corrupted and I have to restart the machine.
This was not happening when I first installed 7, and may be related to having installed 7.5 and 8 trial versions and their libraries.
