ODBC Data Source SQL Server Connection - Login Failed For User

Question

I have moved my database from an SQL 2005 to a server with SQL 2008.

I am now trying to create an ODBC Data Source.

I am using "With SQL Server authentication using a login ID and password entered by the user" and have entered my Login and password. The Login is visible in SQL Server Management Studio under Security-> Logins.

The login also contains the exact properties of the same login in my old server. When I hit next after entering the username and password I get:

Connection failed:
SQLState: '28000'
SQL Server Error: 18456
[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'myUser'.

After reading this: http://support.microsoft.com/kb/555332 I realized that the server properties were set to "Windows Authentication Mode" only, but even after changing to "SQL Server and Windows Authentication Mode" I am still having problems connecting. I can connect with my Windows account though.
