It could really be either, if the server added a plugin since the last teleporter you made. However, the biggest question is, what were you using to fire the teleporter? Constant RS signals leave the teleporter on, and can cause both bounceback and hacking messages.

Update your launcher. You have a rather old version, and it's obviously not working correctly.

The minecraft.net auth servers have been up and down the last few days. Can you be more specific with your error message. Also, that's not a launcher version I've ever heard of. Finally, figure out what your Java version is.

Make sure the bit version of Java matches that of your OS. However, the most common cause of this error is antivirus software interference. I suggest you find out what you have.

This is not a helpful bug report. We need the exact error message. Also, before you do that, read the COMMON PROBLEMS AND SOLUTIONS thread that's at the top of every bug board.

A few questions then: 1) Are you using 64-bit Java? If not, you should be. 2) It's probably not, but is this a laptop by chance? 3) Can you provide a launcher log to look at?

I haven't figured that out, because it's always been grayed out for me. I'll pass this bug report along to the mod pack team if I can, since I'm not sure what's causing it.

Does the launcher allow you to allocate more than that 1536MB? If not, you're still using 32-bit Java. Oh, and there's an edit button - no need to double post.

'Scuse? This is a completely different situation. The OP In this post is being an idiot.

Yes. (See how my response was just as helpful as the bug report you put in the wrong place with no info?)

You. are. evil.

The Anvil conversion is done by Minecraft, so it must be done in-game, yes. Are you sure it reverts your world, or does it just reset a bunch of chunks? The compatibility issues with updating are complex, and often it's better to just start a new world with new full versions.

Then perhaps you should be using the "use latest LWJGL libraries" setting. :)

Update Java to 7u5 (and get rid of the old one(s)). You should probably go grab a new copy of the launcher as well, unless you've done that in the past few days.

Hi, my name is Torezu, and I support this post.

You can't. You can start a new one, and I can close this, though.

Launcher logs, anyone? Java error logs are useless, unless you speak their language. Not too many of us (read: none) here do.

Why would you want to destroy an infinite matter creator? OT: Is there a remote possibility you gave yourself (or someone gave you) an infinite stack of nikolite? If not, it's an EE glitch. There are...many of those.

Kinda the point of my other post. I could have told them that if they'd just posted the logs before I saw the topic.

Crystal chests have been determined to cause massive lag issues, particularly when dealing with certain items. Nikolite has been mentioned. I would strongly suggest replacing them with diamond ones, as inconvenient or aesthetically displeasing as that may be.

You have Tekkit 3.1.2, while the server you are trying to log on to has Tekkit 3.0.4 (matching client 3.0.3). They're not compatible.

Yes, and? You gave us about enough information to figure out what happened, but no clue as to why. Try harder.

This doesn't belong in General Technic SSP. Moving to the LP section.

May I suggest a pair of World Anchors?

I assumed so, and asked the admins to stick a yellow name on him. We'll confirm that when he comes back, but that was his first post here. :)
