Newbie - KS3 Hangup when selecting material

[pigdog]

 I have tried reinstalling the software, but software crashes everytime I try to add material to a surface in models imported from Alibre. ..

I save the models as *.bip files and they initially open up OK, but won't accept material surfaces. The software just hangs up.

Any advice on how to make things work?

Are there any reccomendations in regard of hardware - especially RAM that I might need to use? I have a 2 Ghz Core duo with 3MB of RAM.

Thanks
