@olddude: Of course that the license file looks "funny" as it is encrypted in some way. It is not a plain text file (that is the reason it cost some $)
@airnocker: Even it is named 3.043 only, in fact it is 3.043.062, see attached picture. As my memory serves, 066 had more bugs that were introduced, so it was decided to ditch that version and declare 062 as the last one.
Development of Mach3 finished some, if I remember, seven years ago so our wishes for bug fixes and program enhancements would be just barking in the wind.
