Can't Play SMP with Minecraft Forge

[stephenmac7]

For some reason it seems that I cannot play on an SMP server (of my own) with Minecraft Forge. I have Minecraft 1.4.5 with Minecraft Forge 6.4.2.448 (I have an older version of minecraft and forge because Industrial Craft doesn't support 1.4.6 yet). If it helps: I have Minecraft Forge and Industrial Craft on the Server.

 

Here is the error:

...and a screenshot:

Though I don't have an answer, I've been experiencing a similar problem in 1.4.6. I'm trying to get a fairly large modpack to work on LAN, and though I can get the LAN server up, whenever someone else tries to log in they get that screen. On my screen I see that the person logs in once, and leaves the server twice.

You're connecting to a server with a different version of forge. Update your forge. you have a very old version.

What do you mean, I have a very old version? It's just one before the newest and I must have it to use Industrial Craft (as it does not work on the newest version)

448 just grew a beard and wrinkles and is now in the nursing home.

Update to latest, should work for you.

But it doesn't, I tried really hard to make it work...

There is a really really simple solution here, use the same exact version forge on your client as you do on the server.

Problem solved.

I have the same problem too, when I start a server with the newest forge(6.5.0.486) and login with the client with the same version of forge it gives my this screen too.

No, they do have the same version, though.

If you hit Done... what happens?

It goes back to the Minecraft home screen (Single Player, Multiplayer, Mods, Options, etc)

Put your Minecraft GUI-scale to small and try again, There is an error message but it is situated below the done button. My error had to do with TooManyItems

Didn't work... but I didn't try fullscreen.

Thanks for the replies. It seems that updating to the latest version of minecraft and minecraft forge then using the IC2 beta worked perfectly.
