Exception in server tick loop

Title: Exception in server tick loop

Version: 1_0_3

OS: Windows 8 premium

Java Version: Latest

Description of Problem:

Our server will not run. after it loads the world it stops and gives us an error message talking about something with Atomic Science as far as i can tell. This happened randomly as well the server owner reset it computer because of issues with another program. When his computer started back up and he went to run the server it gave him the error. we currently have four extra mods installed on top of Tekkit. we have The Chocolate Mod, Portal gun, Gravity Gun, and Barrels; all of which where working properly.

well here is the crash report. the only thing we changed about Atomic Science is that we enabled uranium ore to spawn in the Config, which was also working properly.

Note: removing the world and letting a new one generate seems to fix the issue. but we would like to keep our world.

Error Log:

[Chefsbrian]

The problem is a mod that you had has been removed, causing the world to fail to load.

Also, for future reference with error reports, verify that you actually have the latest version of java as opposed to assuming, for latest version is 7-45, you are running 7-21.
