Problem with Communication component2.0

hi all,

Here i am Doing some integration ( navision with a VB Application).
for this i am Using NAS. i got every thing inclides Nas service started, Messages are getting into Messagequeues.

when i try to receive a message from messagequeue i am unable to receive .

it is unable to fire the communication component Event .

[b]OnRun()
CREATE(MQBus);
CREATE(CC2);
CC2.AddBusAdapter(MQBus,1);
MQBus.OpenReceiveQueue('sys125\private$\ToNavision',0,0);


InsertMSMQTestDataRec(Param : Text[250])
MSMQTestData.TextValue := Param;
IF NOT MSMQTestData.INSERT THEN
  REPEAT
    MSMQTestData."Entry No." := MSMQTestData."Entry No." + 1;
  UNTIL MSMQTestData.INSERT;


CC2::MessageReceived(VAR InMessage : Automation "''.IDISPATCH")
InMsg := InMessage;
InStr := InMsg.GetStream;
InStr.READTEXT(Line1);
InsertMSMQTestDataRec(Line1);

Here i am unable to insert the records into the Table MSMQTestData.
but the messagequeue has a Message.
