vxWorks problems

[4057programmer]

I am having troubles getting the vxworks downloadable kernal module sample project working. As I try to get into it it displays the following error code:
The capability VxWorks 6.x Development is invalid because the underlying platform is not available. This leads to unexpected results in Wind River Workbench. Please check the installation
After that I try to select a sample file but there are none up there. I have the WPILib.a file in the vxworks folder, and I think I have all required updates. Any thoughts?
Thanks for your help!

Did you by any chance install Workbench 3.3 from disc 2 without first installing Workbench 3.0 from Disc 1?

No I installed them in the correct order. If nothing else I will try to re-install them again though.
