Segmentation Error when opening files

Hello,

I encounter a segmentation error when opening a geometry file in HyperMesh. The same file reads easily on a computer of a colleague of mine. Is there a way to solve the issue?

Second question is related to backwards compatibility of HyperMesh: If I save a file in HyperMesh 12, can I open it in HyperMesh 11 or older versions?

Regards
