Ok,
It's possible you will have to check the TCP port number for SQL. In the past, changing it to 1433 works (assuming you are using 64 bit SQL).
If that does not help, you may call and open a ticket at
800-945-3355 .
soSo I added those screens in reverse order, but you get the idea.
Restart SQL service and IISreset.
Let me know,
