Fantastic programme, but cant export or print

When I try to print preview or print to PDF i get an error in Java 3D window

Failed to create reference rasterizer 3D device -D3DERR_NOTAVAILABLE

Then the program exits

I am running a 256mb laptop with WinXP
I have the latest Java 6.2 installed (but I used the full installer of Sweet Home 3D with jre)

Any ideas how I can solve this?
