need help with SqlCeConnection and app.config

[Sl1ver]

i can't get the mobile app to make a connection from the app.exe.config but if i hard code the DB path it connects. ConfigurationMa nagerCE is a seperate class

app.config.exe
<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <appSettings>
    <add key="MobileDBPath" value="\Program Files\Mobile\qxAsset.sdf" />
    <add key="WebService" value="http://JM-QwixWHv2/asset/SyncService.asmx" />
    <add key="CSVPaths" value="\Program Files\Mobile" />
  </appSettings>
</configuration>

and here is the connection coding

SqlCeConnection myConn = new SqlCeConnection();
            string strConn = ConfigurationManagerCE.AppSettings["MobileDBPath"].ToString();
            myConn.ConnectionString = strConn;
            myConn.Open();

whats wrong with connection coding?
