Will any of the 4 (!) of you who want help post a launcher/error log? That'd be helpful. Without it, we're shooting in the dark. With an Uzi.

I'm getting kind of sick of repeating this, but here goes again: We can't help without a launcher log. Most errors are so generic that the log is the only thing that shows what's wrong. In this case, though, I think you may just need a .minecraft and .techniclauncher\tekkit wipe and reinstall.

It's the little details that make this funny. Then you go and do something like posting the wrong log...

That's either an antivirus/firewall blocking the launcher, or...nope, wait, that's pretty much it. What are you using?

Try running the .jar instead.

Or if, you know, there was a launcher log. Then someone might help you.

You installed a new version of Java right before this, right? You installed 32-bit Java. Go get 64-bit here.

Errrm, did you even try MCEdit instead of having to scrap an entire world?

Are you sure you have Java 7 installed? That launcher log shows Java 6. Java 7 is needed to run the latest version(s) of Tekkit, or at the very least it's much more stable.

This is the message you usually get when your client is too new for the server, or possibly too old. Make sure you have 3.0.3 on the clients, and the server should be 3.0.4.

You probably upgraded to 3.1.0 by accident. Go into Options in the launcher menu with Tekkit selected and make sure it's set to 3.0.3.

You probably need Java 7.

Bad login means the minecraft.net authentication servers aren't currently working correctly. The missing mods may mean you upgraded to Tekkit 3.1.0 accidentally, or possibly that your antivirus/firewall is blocking the launcher.

Does it have an active redstone signal to it anywhere? That'll shut off a reactor.

Where did all those mods come from? Are they adding a bunch to Technic 7, or are you using a different mod pack?

Yes. Yes you do. Get 64-bit 7u5, and kill everything else that says Java 6 on it.

Huh? Nobody attached anything.

Yes. You can't.

The auth servers are broken - minecraft.net isn't working. Be patient, play single player, or learn how to offline your server and rename yourself. Hint: I don't know, so don't ask me, and it's a pain.

Hey everybody! Look at all those question marks! This must be serious!

You need to post with the Submit a Bug Report button. Otherwise you can't start a new thread. This doesn't sound like a bug, though. Give us pictures of the setup. Remember that for any kind of energy storage box, the dot is the output.

IC2 machines are known to cause huge lag problems. Turn the IC2 sounds off for your client and see what happens.

And don't use "/reload" at any time.

Did someone use "/reload" on the server? Also, are you talking about a wooden gear?

Destructive: Any EE ring/amulet aside from Harvest Goddess' Band (and even that...). Dark/Red Matter tools of any kind. Mercurial Eye, Destruction Catalyst, Hyperkinetic/Catalytic Lens. The list goes on. Dupe: Black Hole Band/Void Ring and Alchemy Bag. Red Matter Furnace. Trans Tablet in heavy lag, sometimes. NEI. OP: Quantum/Gemmed Armor, much of the EE gear.
