I downloaded EO 4.0, and updated both my client and server to the latest (4.1). Now, when I try to login, it tells me either the client or server is outdated. But neither of them are. They’re both on 4.1, and I’ve opened them both via the autoupdater like it said to.
I tried re-extracting the original .rar it came in to start fresh. I still get the same message.
