Keyshot not importing SW 2009 IGS files

[m2tts]

Key Shot will not import Igs or Step files created with SW 2009.

Just worked out with Keyshot support that I needed to switch off the "New Importers" under the preferences tab. Don't know why the new ones aren't working with my system.

I tried to import a SW2010 IGES (118 MB) yesterday.  Took over an hour to import, with 296 "layers", and resulted in a 4.68 GB .bip file that was unmanageable.  Dumped it.  I'll try again by switching off "New Importers".
