Thanks you for the answer, unfortunetely, if if only it was that simple,

It also failed the same way running as administrator, and the DEV9 plugin still not working and cannot recognize my network adapter.
I've saved the pcsx2 log while running the game, here it is.
Am I still doing something wrong or did I missed something ?
Thanks for your time.
UPDATE: I've managed myself to readjust the settings and there is some progress.
I am like one step away from this completely working.
I encounter however the udp port check error, do you have any clue about it ?
Thanks you for your time.
