I am trying to get a website moved from one server to another. I've installed VDF 15 Server on the new server. The 15.0 example webapps run.

But my production app will not run after moving to the new server. I keep getting the following error.


Code:
Session failed to initialize: Fatal error occurred during child process initialization: Internal user count file error. License File is missing. Register your license again
VDF Error#: 28682 in line: 16972.
I have re-registered a couple of times, but still no joy.

Windows Server 2008 R2
IIS 7.0 (correctly configured according to the DAW Whitepaper)
VDF 15.0 Web App

Thanks
