Please provide more information.

1. 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

If you get no error messages and the problem persists after restarting 
the kernel then your Mathematica installation is most probably damaged.
