Keyshot 3 crashes in MAC(Lion)

I got the KeyShot 3 Education version. It crashes every time when I am trying to import a file or even opening a file. Also there is no rendering queue in MAC version.
Very unhappy with the situation!!!!!

This is bug in the Lion system. You have to turn off icon preview in the File Finder to prevent it from crashing.

I try turn of Finder file icon preview, but it's useless!
