Modal Correlation Alignment - Uknown error Occurred

Hello all,


I'm trying to run a correlation solution between an experimental solution and a numerical one.


I import the geometry and the modal file and everything goes well. I can see the animation of the experimental results as well. But when i try to do the alignement between the experimental and the numerical, NX says that an uknown error occurred. 


Does anybody has a clue for this?


Thanks in advance.
