Ok - just downloaded and installed DCM 4.5 for DF 18.

Installed the registration code and it just disabled all my valid connectivity kit license for my full DF 18 development license !

During the installation I got several popups that VDF 18 license code is invalid. Now my development machine is dead. I can't compile or run my DF 18 apps.

This is the message I saw during installation and now the message when I attempt to run my DF 18 apps.
