Midi dump to Virus B

[hardcharger]

Hi everyone. Im new here, have had the Virus B for a week now.

I have a (common?) problem with my Virus B.
I am trying to load a new bank into my Virus, been trying some different but with same result.
Been reading the manual, checked the FAQ on accessmusic, been searching and reading the MIDI Dump instructions here.
Computer is sending on the right channel, my interface is blinking as it should, and on the Virus display a "SE" is blinking.
But nothing is stored, eg. nothing is changed and the originalbanks it untouched.
I've setup Cubase as it says in the helpfile in Cubase. And I think I've successfully recorded a bank from the Virus to Cubase.

Here is what I set up:
Virus:
Midi dump RX Force to bank A.
Midi dump TX Singlebank A.
Globalchannel: 1 (singlebanks is playing on midichannel 1)
Panel: int+midi
Mulitprogramchange: Disable
Deviceid: 1
Midicontrol:
Lopage: Contr, Hipage: Sysex
Computer MIDI output -> Virus MIDI in
Computer MIDI input -> Virus MIDI out.

Midi interface:
Audiotrak Midi Mate USB. New. It looks to work fine.

Computer:
Windows XP with Cubase SX2.
Tempo Track: 120 or Tempo Fixed: 60
Preferences:
MIDI:
Midi thru active, ticked
Chase events; Note and Sysex, unticked.
MIDI FILTER:
Record, everything unticked.
Thru, only Sysex ticked.

I have also tried using Sounddiver, wich looks to be a nice utility, but it doesnt work any good either.
When Im trying to transmit, i get a error on Virus display "SYSEX with wrong checksum". And that made the title of the patches in A bank dissappear, so I had to reset the virus.

Please tell me everything that I should try, maybe I've missed something important? Maybe i have to be in a certain place or patch in the virus or press store or any button?
I want to know everything you come up with, even easy stuff. I am a newbie to the virus and midi dump's.
