It did work. I just erased the Tekkit folder inside of .TechnicLauncher and had it re-download a new one. I cannot use my old worlds, but whatever. Thank you for the help.

oh... no I just changed the level.dat stuff will generating a new world entirely fix this problem and allow me to play again?

I did what I think you told me to do, by deleting the current level.dat and renaming level.dat_mcr to level.dat Is that what I was supposed to do? I made a copy of the world, in case I messed up, which I did. I now have an error report upon launch. I tried to capture the error report but it goes away quickly.

Thank you. So to clarify, I cannot use my old worlds while running Anvil?

The first time I have experienced this, was today, June 9, 2012.

Title: Crashes due to &quot;ANVIL&quot; Version: 2.1.1 OS: Windows 7 Java Version: 1.6.0_31 Description of Problem: Tekkit crashes after playing in game. This error has only started to occur after the Tekkit launcher upgraded to the new minecraft form, &quot;Anvil&quot;. I have done all in my knowledge to reset Tekkit, and have lost my worlds due to this. I want the developers and modders of Tekkit to know that there is a huge glitch with the Anvil Tekkit. If possible, please help me return my Tekkit to a working version. Thank you. Error Messages: Crashes... Error Log:
