Rayfront - license not found

Hey,

I downloaded a prog called Rayfront and installed it - then installed
the license key as instructed but when I tried to appload the arx into
the autocad it keeps saying that license key not found.

When I open the Rayfront program it opens fine but when I try
importing a dxf file into the prog it says "no surface prinmitives
found in file"

Any similar experiences?
I´m running autocad 2002.


thanks.
Masa

 

Yes...it´s a rendering/ray tracing program.
I did a test file which contained a solid, boxes made of faces and
regions, but still the same thing.

Here´s more on the program:

I mailed the same question to the schorsch -guy but my computer
crashed when I sent the mail so I´m not sure if the mail left...better
mail it again.

thanks anyway,

Matti
