Unbelievable - License error

[ticiana 0]

I bought a 737 from PMDG installed and never had a problem. Today I instaled the hotfix 2916 and got surprised, the airplane stopped working and the software asked for a license and when I type my license it says its not a valid. What should I do? How can I solve my problem? Ticiana. will@netbandalarga.com.br

PMDG will have to possibly "reset" your activation. Put in a ticket http://www.precisionmanuals.com/pages/support.html. You can also try a uninstall and reinstall of the product with the hotfix then add your liveries back.
