There is not errorlog I would assume, the game does not crash or anything, it just has a really low frame rate until i close it, where can I find it?

When I try to create a new 3d model I get the following error: "error opening prototype model file"
c:program filest-flext-flex parametric cade 11programtemplateansi 3d front right bottom workplanes.grb
Any ideas?
