Crystal Reports create jdbc connection hangs Crystal 2008

Message

   Hello;

I could do with some help as i'm pretty well stuck.

I'm trying to connect crystal report 2008 CR developer version 12.0.0.683 to a MSSql server 2005 Database on our network for jdbc.

There is jdbc driver sqljdbc.jar with installation under "C:\Program Files (x86)\Business Objects\Common\4.0\java\lib\jdbc"

I then opened the CRConfig.xml in "C:\Program Files (x86)\Business Objects\Common\4.0\java" and added "C:\Program Files (x86)\Business Objects\Common\4.0\java/lib/jdbc/sqljdbc.jar;" after the last semicolon just before ${CLASSPATH}

I then open Crystal reports, standerd report wizard, create new connection, JDBC (JNDI), I then enter my DB URL: " jdbc:sqlserver://dbs-mssql2k5:1433;DatabaseName=IBM"  and driver class "com.microsoft.sqlserver.jdbc.SQLServerDriver".

Then next, then I enter username and password, selected the database wisconsin_prod from the list in Dabase dropdown box. Then click finish, then ,crystal hangs.

Since then If I try to do the same, I am not able to see the list of database from database dropdown. I think the connection was broken. 

Any idea? I think I have done everything right. 

Thanks for the help,
 Jean
