Both of us are on wireless, but his game works and mine doesn't. It's not a connection issue because, as I said above, I can download huge files in a short time and get on the net just fine.
I already tried copying his RoM program folder to a hard drive then copying it to my computer. No change. I keep a backup of the RoM program files folder so that in case Windows takes a dump and I have to reinstall Windows and all my other programs, I don't have to re-download all the updates all over again. That backup file was current.
I posted in a thread similar to that about a year or so ago, and there indeed was a problem on my route to the game servers. But that's not what's going on here. If that were the problem, then my friend's computer would not be able to get through either, since we are on the same network right here in the same house. The routes to the game server would be identical, so if I couldn't log in, then he wouldn't be able to either.
I am uninstalling the game so I can reinstall it again. I have deleted the hidden game settings folder in My Documents just to make sure. After I get it reinstalled, I'll update here. It's probably going to be a while before I can update this, because this time I'm going to just let the game download the updates instead of restoring the backed up program files folder.
This is annoying as hell because I just bought a bunch of dias. And not only that, but the XP/TP event is going on right now.
