Opmanager 9 x SQL Express 2008

Opmanager 9 x SQL Express 2008

Hi,
 
I install MS SQL 2008 Server with instance Opmanager. W hen I do the installation of OpManager 9 ( in the Windows " configure the sql server details" ) the message: host name or port number is incorrect.
 
I checked and the sql is using port 1433 and the ip of the server is 10.3.0.12 . And the sysadmin user belongs to the Administrators group of the server .
 
Help me!
 
*My english horrible.
