I have a account on www.Fastbob.com and am trying to install DotNetNuke 4.0.2 to the /Home directory (So it would be located at http://www.MySite.com/Home) But it's not working. I put the right stuff in the connection string and i get this error

DotNetNuke Upgrade Error

The Assembly Version ( [ASSEMBLYVERSION] ) does not match the Database Version ( [DATABASEVERSION] )

ERROR: Could not connect to database.

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

my connection string is

<add
      name="SiteSqlServer"
      connectionString="Data Source=.\SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|Database.mdf;"
      providerName="System.Data.SqlClient" />
    <!-- Connection String for SQL Server 2000/2005
    <add
      name="SiteSqlServer"
      Server="whsql-v08.prod.mesa1.secureserver.net;Initial Catalog=DB_50942;User ID=DotNetNuke4;Password=mypassword"
      providerName="System.Data.SqlClient" />

in my hosting manager the SQL Database looks like so

SQL Server Database Information
Database Name	DB_50942
Host Name:	whsql-v08.prod.mesa1.secureserver.net

any ideas?
