Discover and Procurve

Hi everybody,
Can you tell me how to set up the Dude and HP Procurve switch ?
SNMP v1 & v2 on the switch enabled, IP assigned. When i discover the network i see all devices linked to the subnet. But when i click on the Procurve icon, i can see in the snmp tab all the interfaces with mac adresses of the devices. I’ve got 3 pcs of Procurve 2626 switches, SNMP enabled with public community default set. But The Dude cant read from them that the devices are connected.

I used the Dude earlier version and changed hardware. When I reinstall the Dude - the discover show mess.
Can anybody tell me what should i do to set The Dude to work with HP Procurve switch ?
