Back pedal

[propwash]

I dont have the time to figure out why my ver 3.0 3.01 crashes every other stl i load. i want the version before 3.0 reinstalled so i can finish my work , anyone know how i can do this?

I imagine you've already figured it out...
I back-peddled to 2.x (had too many problems with 3.x).
I completely uninstalled 3.x first then installed 2.x... no problems
