WizCon connecting to OSI PI OPC server

Basically I am trying to get data off a PI server and I am having difficulty getting Wizcon to connect to a Beta version of an OPC Server from OSI. Is anyone else using this OPC server? and are you having problems with it?

I'm in hot water right now because I have never had problems with Wizcon but the client doesn't seem to care. Since they got the OPC server installed (which is still in beta) it must be WizCon, it couldn't be a flaw in the BETA.

Thanks,
Nic
