Is Matlab R2014b license different from R2014a?

I get a license manager error -25 when I attempt to run R2014b after updating from R2014a. Is a different license file or LM configuration needed for R2014b?

License Manager Error -25 error can occur when the version of MATLAB is newer than the version of the license.dat file on the server machine. To resolve this issue, update the license.dat file on the server machine to the latest release that you are licensed for. Please contact your license administrator to make the update.

The license.dat file on the server machine is located in:

$MATLABROOT/etc ($MATLAB\flexlm for releases prior to R2010b on Windows)

(where $MATLABROOT is the MATLAB installation directory)

NOTE: Once you have made changes to your license file, be sure to restart the license manager for these changes to take effect. For more information on how to restart the license manager, see the Related Solution linked below:
