Starting with GBUI problems

I have the GBUI project in Eclipse but if I try to run any test classes I get this error.

I must be missing something because it says I have an outdated jar file. Any help would be appreciated, thanks!



//EDIT: Sep 27, 2009 I got the latest code from SVN, and the tests compile.

This happens if the dll is not compatible to the native dll. For example you downloaded a new lwjgl-version using the new lwjgl.jar with the old DLLs.
