Is the Simplify3D team relying on users to troubleshoot each other's problems? I would expect this from free open-source software, but for $150 software?
There are pages and pages of requests for help in this section and half aren't even responded to at all, and none are responded to by Simplify3D.
Simplify3D, get your act together!! We paid for this software, you just created a new release that is causing problems for people. THIS is the time you are supposed to be doubling up support.
