[DEVART][ODBC][PostreSQL]Trial period is expired

[DEVART][ODBC][PostreSQL]Trial period is expired

hi,
last year i tried devart odbc driver for postresql on a server with windows2012 R2, it was for a POC with an instance postressql for test.
now i want to industialise solution and before buy devart odbc driver, i want to try access on the same but with the instance postgresql to industrialise.

On the server I uninstalled the existing driver version and reinstalled the latest version 4.04.00.00.
When I do a connection test I get the message "trial period is expired"

How to test connection with this driver ? 
Thanks
