Im trying to load a effect in SlimDX, but I get a error when I try to get the ShaderSignature. The error-code:

E_FAIL: An undetermined error occurred (-2147467259)


This is my code:

   EffectTechnique tech = this.effects.GetTechniqueByIndex(0);
EffectPass pass = tech.GetPassByIndex(0);


Any idea?

3. Depending on your other code, you need to install the Debug Runtimes (specifically if you're using CreateWithSwapChain from one of the demos). This could also help get you more information.
