     Mathematica licenses are limited.
 
 There exist two types, MathKernel and SubMathKernel licenses. Every sequential job you start will
-consume a MathKernel license of which we only have 39. We do have, however, 312 SubMathKernel
+consume a MathKernel license of which we only have 61. We do have, however, 488 SubMathKernel
 licenses, so please, don't start many sequential jobs but try to parallelize your calculation,
 utilizing multiple SubMathKernel licenses per job, in order to achieve a more reasonable license
 usage.
