Did you try quitting the kernel, than re-evaluating these expressions (after loading the package, of course)? Does this happen every time? 2. Do you get any error messages when loading the package? 3. Are RandomArray[] and NormalDistribution[] defined? Try evaluating ?RandomArray ?NormalDistribution If you get no error messages and the problem persists after restarting the kernel then your Mathematica installation is most probably damaged. Szabolcs
