[SOLVED] Setting up BugTracker.NET complete noob

This is my first ASP.NET project and I'm stuck right away.
I'm setting up a bugtracker on a remote webhotel but I can't get the connectionstrings to work. If we say that my host is called hosting.org and my website would be www.trallala.com
what do I have to change in this script?
<configSections>
</configSections>

<system.web>

    <!--
    BugTracker.NET is not compatible with Session serialization.

    <sessionState mode="InProc" timeout="120"/>

        ********* QUICK START *************

        If you want to get started quickly, then just change the following
        and then try to log in:

            ConnectionString
            AbsouteUrlPrefix

        After you can log in and create a bug, then you probably want to
        set up the email integration.  Set up the following:

            ErrorEmailTo
            ErrorEmailFrom

            NotificationEmailEnabled
            NotificationEmailFrom

            And your SMTP settings below.

    -->
    <!--
        Change this to point to your database
    -->

    <add key="ConnectionString" value="server=(local)\SQLEXPRESS;database=btnet;user id=sa;password=x;Trusted_Connection=no"/>
    <!--
        Used when creating absolute href's.  For example, in notification emails.
        Don't forget trailing slash!.
    -->
    <add key="AbsoluteUrlPrefix" value="http://127.0.0.1/btnet2/"/>
    <!--
        You can turn the logging and emailing of errors on and off.
        Log file name is "btnet_log_yyyy_mm_dd.txt"

        For the LogFileFolder setting, if you specify the folder starting with a 
        drive letter or the \\ that indicates a UNC path, it's treated as a full path.  
        For example: c:\\something or \\somemachine\something

        Otherwise it's treated as a path relative to where you virtual directory is
        located.

        LogEnabled turns on and off logging as a whole.
        LogSqlEnabled turns on and off just the logging of SQL statements, but
        that's about 98% of what gets logged, so if you want to reduce the
        volume, turn that off.
