INTERNAL CAM KERNEL ERROR

[seayhiperformance]

All the sudden when trying to generate a simple toolpath in 2d contour I am getting this error. I have not changed any settings and have never had an issue until now. Nothing I have tried seems to help and none of the posts about this issue I have searched give any answers.

If you're running Windows 7, this is likely the issue.

IF you are running Win7, we did announce (almost 2 years ago) that support was being discontinued for that OS. Why? Microsoft ended their support of it, and we don't put testing into obsolete operating systems.
