Bobcad v25 keeps stops working in simulation

v25 whenever I run a simulation with more than one feature at the end of the first feature it stops and an error message that the program has experienced an unknown error and must shut down. If I only have one feature it runs to the end just fine. I am using windows 8.1 bobcad mill v25

I never did like V-25

Does your PC have a dedicated graphics card or an onboard? Have you updated your graphics drivers?

Those are the areas I would be looking to resolve the issue.

Yes, there is a dedicated graphics card I will check the drivers thank you.

The drivers are up to date. I still can’t rum multi-feature simulations.
