Polyscope freezes calibrating with Sick inspector urcap

hello, i have an issue with my CB3, i have a sick PIM60 sensor mounted and connected to the robot, i have ran sopas on pc.
the camera says connected and i am able to see the live image, but when i calibrate it seems to work fine until i send coordinates to robot, then polyscope freezes and i cant do anything anymore, sw is 3.15. has anybody experience this and know how to get around it? it has worked on the robot before, but the urcap has been gone and reinstalled in the meantime, can it work with an older version urcap maybe? all advice are cherished.

br. Martin.
