Yep, it turns out I do use a router. Sorry to bother you again, but where is the router setting?
Also, is there something I am missing, because I looked at another thread about a person who had the same problem and their problem was the server. But am I missing something? Do I need GameSpy Arcade or some other program? SFC3 online worked for me when I still played like a year ago, but now it doesn't work.
Oh and by the way, could the problem be because I am using a backup CD? I misplaced the original disc so I am using a backup CD, but I still have the original CD-Key. Could that be why I cannot connect to the Direct Play Host?
I have virtually no experience with routers. Were you using a router when you last played SFC3? If so, and you haven't done anything to your router, then there's no reason the router is causing the problems. If you weren't using a router the last time, then you're gonna have to configure it. But, as I said, I have virtually no experience with routers. Took me 2 days to figure out how to get into my router settings, and that was nearly 2 years ago.
You don't need Gamespy to get onto the D3. And as for your backup disc, unless the disc is damaged or the copy corrupt, there's no reason why your problems are caused because you reinstalled the game using a backup disc and not the original. I made several backups of my install disc and put the original away for safe keeping.
