BobCad-Cam Simulation Question

While learning how convert photos into engraving g-code.
It takes an amazing amount of memory ! The program made an odd move during simulation, then stopped.
After that,, even very small programs do not work in simulation. When i try to run them,, it just beeps.
I am sure it is a simple fix,,, I just do not know how.

Sure sounds like you got a "crop Circle"
Many threads on that here
but why simulation would not work on other smaller different programs,,I don't know
Do you have Preditor ?What does it do ?
