Please, help me. software problem error

[unreal7204]

I was unwrapping the uv with max. Press the pelt map button and the editer window will pop up. Press the start relax button there and the screen will suddenly shut down. It's the same no matter how many times I do it. I've tried updating AMD and adding the max program to the window firewall as it says on Autodesk, and I've tried how it appears on the internet, but it still has an error. Please let me know what the method is. help me Please...what should I do....?

It sounds like there are errors in the mesh file you are working with. Have you tired to rebuild it? Have you tried the same unwrapping on another mesh object? If it works on a simple mesh like a generic sphere then it means that Max is not misbehaving.

Have you run 'STL Check' on your mesh, and if there are errors, fixed them until there are "none" and then tried the 'Pelt' again?
