Yep, I agree 100%, that's what's weird to me as well. I've always managed to do my own software troubleshooting (having a bachelor's degree in computer science, I'd feel lollipop if I didn't), but this time it seems to be beyond my grasp.
The first crash occured mid-project, while I was working on a bass cover I had started last month. The Cubase project opened fine as usual, Native worked, everything worked; then after a take, I tried to pull up Native's interface to fiddle with the tone a bit, and that's when it first crashed. It didn't happen after a restart/update (unless something was happening in the background while I was working), and now it doesn't work *at all*.
