Hi Matt

Sounds like you are having a nightmare with this one. I have never had this problem but i will put a few ideas your way.

If memory serves me right does it not give you the option screen first before it asks for the in code.

What in code calculator are you using as i have had problems with cytoworks codes being wrong.
Are you using the longer code for module initialization [different reason for access]

Maybe try telling it its had a new cluster before trying to match them up. hth

Regards Ian
