I am also encountering this issue.
I have installed the Gentool software, I see the Gentool UI when launching the title as normal.
My IP shows 192.168.0.65 when viewed via the Network option.
The CMD prompt did show gentool installing onto the title.
I receive the online service cannot be connected prompt after viewing the checking for updates message for 60-90 seconds when selecting the Online Option.
I would love to join the Generals online community. Please help if possible.
