Problem with CNC Toolkit running on GMax

Hello to everybody,

I am trying to use the CNC Toolkit for a 5-axis milling machine. When I export a toolpath (Post Process Toolpath) the program (GMax) gets stuck and an error message pops up (see attached image). It happens with any sort of shape when I'm using the 5-axis configuration (It doesn't matter which mode the machine is on, if it's a 5-axis mode, it doesn't export the Toolpath/generate thte G-Code).

I've exported the same Toolpaths with the 3-axis configuration and it does indeed work in that case, but it's not what I'm looking for. I'm using the "CNC-Toolkit-4.34b.ms" version of the Toolkit, which I doubt is the latest.

Any help is appreciated,

Borja.
