When upgrading to a newer version of Matlab, you also have to upgrade your toolboxes.  So if you were using the Stats toolbox in some earlier version, this will not work in a newer version.  Unless your hacking capabilities are off the chart.....

So, if you got yourself hooked on the stats toolbox with, say, a students edition.  Trying to move that toolbox into your new version's folder or path will not work.

$800-$1000 will do the trick.
