This error can occur for the following reasons:

1. 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. Contact your license administrator to make the update.

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

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

(where $MATLAB is the MATLAB installation directory)
