problem in viewing MATLAB help documentation !

Hi everyone,
I am using MATLAB 2013a. Yesterday, I got a problem in viewing help documentation. When I highlight a function and press 'F1' key to get help, the help window is displayed without any text formatting !
Here is a sample of what I got; I hope someone can help me fix this problem.
Best Regards.
