Gaming Call Of Duty online

[giacomo1978]

Excuse me, please..
Do you know how to operate and play online with;

Call of Duty Black Ops
Call of Duty: Modern Warfare - Reflex Edition
Call of Duty: Modern Warfare 3

I always get error 23400.
I use a hard drive and use wiiflow.
It worked before, then after formatting the pc I no longer remember how to set it.
I seem to use the gct codes and activate OCARINA in the loader settings, but it doesn't work.
What can I do, please can you help me?
Please for me it' I miss it so much.. I don't remember the steps that need to be done..
What can I do?
Thank you.

I seem to remember that you had to install an update through the Shop channel to be able to connect online in those games.
