SNMP Traps not shown correctly

Hello,

I am trying to configure PRTG to parse trap messages codes received by Double-Take (from VisionSolutions.com).

This is partial content of the DTMIB.MIB definition file (I placed that file under '\PRTG Network Monitor\MIB\' dir).

----------------------------Start Here--------------------------------------------------------------

-- MIB Definitions for Panther Double-Take

   DTMIB DEFINITIONS ::= BEGIN


   IMPORTS

       enterprises, Counter, IpAddress,
       TimeTicks, Gauge				FROM RFC1155-SMI
       OBJECT-TYPE				FROM RFC-1212
       TRAP-TYPE				FROM RFC-1215;

-- This MIB module uses the extended OBJECT-TYPE macro as
-- defined in [14];

   nsi            OBJECT IDENTIFIER ::= { enterprises 2592 }
   nsiDoubleTake  OBJECT IDENTIFIER ::= { nsi 3 }

   dtGeneral      OBJECT IDENTIFIER ::= { nsiDoubleTake 2 }

        "Number of mirror ops generated by the mirror driver."
       ::= {dtGeneral 3}

PRTG doesn't parse the traps and I am getting generic results.

Any idea how to make this happen?
