ISDEV: The product license has been corrupted

Hello,
yesterday I have installed IS2015 on VM without license key.
I wanted to test it before I put IS2015 on developer PC.

Today I can not start IS2015 any more.
It comes following error message:

---------------------------
InstallShield
---------------------------
The product license has been corrupted. You must repair the license before you can continue. Click yes to repair now.
---------------------------
Yes No
---------------------------

---------------------------

Thank you for choosing Flexera Software
------------------------------------------------------

Internet connection is established.

What could I do?
I can not continue my tests.
