HELP! Can't start Combustion on my Mac

[takigawa]

Hi, I downloaded the combustion demo from discreet's website. I have a B/W G3 with 512G RAM. When I click on combustion, I get an error type 3 (and sometimes error type 2). I did allocate the required RAM to it. After installation, do I need to place anything in the extensions folder? I even re-downloaded the demo version just incase it had been corrupted- still no luck Any advice???
