SIOC Monitor blank/empty

Hi guys.

I am experiencing some problems with SIOC and I hope you can help.

When SIOC starts up all cards are recognized with correct IDX's and so forth.

But when I open the SIOC monitor no cards are shown on the list in the monitor. So I am not able to select any cards in SIOC monitor.

At this point I have i USB-expantion card (With 2 master cards), a servo-card and the OC MCP connected.

Furthermore in SIOC is I click "Reload" I get an error: "Thread error: Access denied (5)"
(Actually 'Access denied' is written in my own language Danish so I might be something slight different in English).

Can anyone figure out what is wrong with SIOC?
