No Gcode saved

Dear forum users, dear Joakim,
Madcam at once does not save the toolpaths anymore. In the Postprocess window it says it did save the toolpath file, but nothing was saved. Also tried saving to a directory directy in C:// and to USB stick, all to no avail.
Can anyone help please? I have a valid Madcam license.
Thanks, Maarten

Dear all,
I am pleased to say the saving problem has been solved. I removed all madcam layers from the Rhino file then saved the file. From there I closed all programs, restarted windows and then I created the toolpath again. And I could save the gcode file again! No idea why this happened.
cheers, Maarten
