Civil Cell Junction insert cause crashes

Hi

I am trying to insert a Civil Cell junction, but the program crashes every time.

I am using 2d seed file with 3d reference file with terrain and geometry.

Could these error become because of the chosen geometry from reference? It is no problem with the corridor and ref. geometry thought.

I am using PowerCivil for Denmark  V8i vers. 08.11.09.497

Regards

Sigfus
