Help needed with 3ds max!

[moo10032]

I've been struggling with this issue all night and no solution in sight...

I have the Space Navigator and it normally works perfectly fine. Tonight it stopped working though, it still rotates the view in 3dsmax but any object I'm viewing will disappear, it is not view port clipping, they simply disappear... When I use the manually built-in view port controls with the normal PC mouse, the view port works perfectly fine, but the second I touch the 3D mouse the objects disappear! I am hopelessly stuck on how to fix this, I've un-installed and re-installed, updated graphic drivers, any ideas at all on how to fix this...? My last resort is to format my PC but I want to avoid doing that and use my time to work in 3ds max vs dealing with a re-format...

PLEASE HELP!

Have you done a clean install of our driver?
