I have just finished installing Matlab 8.2 on OS X Mac. The installation went perfectly fine, but from the first time I tried to run the software I am getting this error. I followed these recommendations: http://www.mathworks.com/matlabcentral/answers/97930 seems my connection to the server is good (can ping it) and I don't know what else I can check. Here is some more information on the error message I am getting:
License checkout failed. License Manager Error -15 MATLAB is unable to connect to the license server. Check that the license manager has been started, and that the MATLAB client machine can communicate with the license server.
