one of the post processors won't function

The mazak L32B post processor asks for the program number when you run the processor to transfer to Gcode when you hit ok it throws this error code

An unexpected error has occurred:
…ram Files (x86)\SheetCam TNG\posts\Mazak L32B.scpost:71: attempt to compare nil with number
This error occurred on line 1273 in file …\Camlib\postmacro.cpp)
Post processing failed

we have used the dynatorch processor with no issue

Give this version a try. Save the attachment to your computer then run SheetCam and go to Options->machine->post processor. Click on the ‘Import post’ button. Using the box that appears navigate to the post and open it.

It ran correctly however it reached an evaluation limit at 5.

That means your copy of SheetCam is unlicensed. If you have a license try reinstalling it. If not you will have to purchase one.
