Found it myself,

I started to delete sections of the program and it appeared to be in a drilling section.
In one of the sections i used a G73 but with a Q0 and Q is not allowed to be negative or zero.
Maybe its possible to generate a more detailed error like "Q not allowed to be negative or zero" in a future release?
With G2 and G3 it also reports missing IJKR (At least during the program not sure during loading).
Best Regards
David
