I have been an S3D user for several years. They have still not been able to fix the corruption of profiles. That existed in 3.x and continues in all versions of 4.x
If they think anyone is going to buy a new version when they haven't been able to fix ongoing and work interrupting failures and fff corruption, then the Simplify3D owners and managers are quite delusional.
I have spent too much time today with the error message that Simplify3D has stopped working. There is no clear recommendation of how to save an existing profile and use a saved profile to create a new one. It happens mostly when there are multiple processes and after you save as new process.
A royal PITA..
