Set a viewport to Explorer or Netview, and maximize the viewport.
In the Data Management preferences, enable the scene debugging preferences:
Disable all geometry operators on load
Detect corrupted polygon meshes and clusters upon load/freeze
Skip loading of floating objects
Merge the scene. If you still cannot load the scene, then the scene is probably corrupted. Check the Backups folder in your project: by default, Softimage keeps the last four versions of your scene in the Backup folder of the project.
If the scene loads, you try to isolate the problem. For example, delete half the scene elements and save the scene. Then try to open this new scene. If that scene crashes, merge it into a new scene again, delete half the scene elements, and save the reduced scene. Repeat until you find the problem.
