Business Graphics Problem

I am working with business graphics in WebDynpro. I have created an application step by step with a tutorial I found in NWDS. When I run it, it gives a page with a colorful image saying "Graphics Rendering Problem". I also ran a sample WebDynpro application which has been loaded to our engine called "SimpleGraphics" which does the same thing. Do I have to set something up in order to use Business graphics. I have looked over the IGS, and it looks to be running. Any help would be appreciated. Thanks.
