The only thing I have installed is Forge, and whenever I to create, or go into a world I already had, it crashes. And I have no idea why. I've got the recommended version of forge installed.Any help at all would be appreciated.

When I try to log into the server I play on, it gives me an error; "Failed to very username! [internal.error Java-Net.UnknownHostExpection: session.minecraft.net]"
Yes my client IS modded, but I don't think my mods have anything to do with this error, so I posted here.
If you have any idea on why this is happening or how to fix it, please let me know.

Any idea when the server will be back up?

Guys, the hacker problem has been resolved, you can come back now, the admins will give you compensation.

Great server. Amazing staff and players.
All in all? 9.5/10

Come on guys, we need more players!

Great server, I love it.

I used the EXE file to install it, but when I open Minecraft, there are no changes what-so-ever.

The same thing happens to me, glad to know I'm not the only one with this problem.

EDIT: Just to clear it up, I've used the link someone provided a few pages back that's an update of this mod for 1.3.2
EDIT 2: I fixed it. I uninstalled my older versions of Java and updated to the newest one and reinstalled the shaders. Worked like a charm.

I don't know what's wrong. I was climbing up a pyramid and then it disconnected me because of an "internal server error" and it won't let me back in.
This is the error thing it said.

Hello!
I'm starting up a small hardcore survival server!
No rules, everything goes.
requires smart moving mod for multiplayer, if you don't have it you can get a minecraft.jar with it already installed at this link: http://www.mediafire.com/?ll995k645t8q94v
ip: 204.237.0.73The map is custom made btw.Greifing IS frowned upon, but allowed.And guys, please try to not get too carried away with killing people.

Maybe you fried your video card? or you are just running out of memory.
Probably the video card,Though.

Loving the server,Hopefully this server stays up!
