BOBCad 33 Mach3_3x_OEM missing

Just started working with BOBCAD 33 again. Was pulling in an old job that always worked in the past. SW said the machine was missing and to pick a new one. Was using Mach3_3x_OEM. Looked at the list and selected Mach3_3x_Mill because this is a 3 axis milling job. The SW will not compute a tool path. How do I fix this?

Are you getting an error message when trying to compute the toolpath? What does the error say?
