"Startup Class Loader Error"

Whenever I load up Matlab, I keep getting this warning:

I've noticed that in some of my apps (the Signal Analyzer), I cannot save my session or my plots. Do I have to reinstall Matlab to fix this issue?

Hi,

As per my understanding of the issue, this error may be resolved by regenerating your MATLAB preferences. A set of instructions regarding how to locate and regenerate the preferences can be found at the following MATLAB Answers link: http://www.mathworks.com/matlabcentral/answers/99625-how-do-i-regenerate-my-matlab-preferences
