Quote from Phynix0228

Did you tried to join a server without the two mods?, and which mods are you trying to use in multiplayer?, maybe it's crashing because the mods you want to use is not updated yet to 1.4.4.

Yeah, I tried to. I'm using Optifine and Too many Items Mod And yes they are both updated.

Plus, I am doing fine on Singleplayer.

I have an error to get on multi-player as well but mine happened with or without mods and the single-player worked fine
the error is as follows:
Failed to login: java.io.IOException: Server returned HTTP response code: 503 for URL:
http://session.minec...3f22321c463117e

any ideas as to why?

Urg! I have this error too! It would be really helpful if someone knew how to fix this...
I'm so bored right now because I go on multiplayer A LOT.
