Hello,
Can you please add more detail to your question?
I am also facing this same issue with my hyperworks account it once showed that there is a segmentation error in importing the model and after that the application gets close. Now whenever I am importing any catpart after opening the Hyperworks it is getting close without showing any tab or anything.
I would take a look at this article to start
