Error on BizTalk Server 2004

Hallo, I m trying to invoke a file trough BizTalk Server 2004 and Commerce Gateway 4.0 to Navision 4.0 and I get the following error message in the event log: --------------------------------------------------------------------------------- The adapter failed on an attempt to transmit a message going to send port with the address “ (CRONUS Italia)”. Details: “Unexpected error in Commerce Gateway Custom Adapter. Original error message: Object reference not set to an instance of an object.
