License problem after reinstalled the software DS-5 AE

Hello,

I uninstalled the DS-5 software and the I installed the new version.

My License Activation Code is: P34E2-07160-3E377 (November 2017)

My Product is: ESW-SOCEDS-DS5-FIX

It seems to find my license but when I compile the first example I got a license error.

What can I do?

Thanks for your help
