Render to texture MAXscript error

IslandDreamer

I'm using Max 7.1 on SP2. When trying to render to texture, I get the following error:
--Unknown system exception

The following line is highlighted in the MAXscript window:
mtlInstance = DirectX_9_Shader effectFile:fxFile

I've tried repairing the 7.1 installation, but I still get the error. Any ideas what's going on?

What graphics card do you have and what rendering mode are you running in? Use -h to make MAX show the renderer selection, try some other mode.
