'SqlCeException - A Parameter Is Missing' After Migration To SQLServerCompactEdition 3.5

Hi,

after migration my project to CF 3.5 and SQlCe 3.5 I got the following error message:

System.Data.SqlServerCe.SqlCeException - A parameter is missing. [ Parameter ordinal = 1 ]

I'm using the same code:

Public Sub Update(oSqlCEConn As SqlCeConnection, oSqlCEAdapter As SqlCeDataAdapter, dt As DataTable)
...
Dim cmd As SqlCeCommand = New SqlServerCe.SqlCeCommand
cmd.Connection = oSqlCEConn
cmd.IndexName="UK_IVCTAMOBILE"
cmd.CommandText="INSERT INTO IVCTAMOBILE(PKey,Status,Dfu,Lu,BusinessModified,BusinessModified_T,IvcTAMetaPKey,InitiationDate,IvcMainPKey,Accounted,Amount,SdoMainPKey,BpaMainPKey,PaymentMethod,InitiationDate_T) VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)"
oSqlCEAdapter.InsertCommand=cmd
oSqlCEAdapter.Update(dt)
...
End Sub

I migrated the Database with this program:

Public Sub Upgrade(DB)
Dim sPath As String
Dim engine As System.Data.SqlServerCe.SqlCeEngine
sPath = System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase
sPath = sPath.Substring(0, sPath.LastIndexOf(""))
engine = New System.Data.SqlServerCe.SqlCeEngine("Data Source=" & sPath & "Test.sdf")
engine.Upgrade()
MsgBox("Finished")
End Sub

Any ideas?

Thanks,
Stefan
