MathWorks Licensing Error 10 indicates that one or more of your products has expired in your license file. It does not necessarily mean that your license in general has expired. When the entire license expires, all products on that license expire and can no longer be used. 
 How can I tell if my license, in general, has expired?
If you are unsure if your license in general has expired, view your licenses in the License Center on mathworks.com. You can tell if your product has expired if its Term is Annual and the Service End Date is before today's date or if it is a trial license and the End Date is before today's date. If your product's Term is Perpetual, then your product does not expire.
