Please help us help you:
  1. What product(s) are you using?
  2. Describe what you were doing just prior to receiving this error?
  3. Can you post your MATLAB code or a screen shot of your Simulink Model?
Thanks!

@Rick: I like your matter-of-fact style to answer questions, which cannot be answered. This is valuable for the forum. +1
