Minecraft has stopped running because it encountered a problem; Unexpected error

A full error report has been saved to C:\Users\Comp\AppData\Roaming\.technic\modpacks\tekkitlite\crash-reports\crash-2013-12-26_22.58.48-client.txt - Please include a copy of that file (Not this screen!) if you report this crash to anyone; without it, they will not be able to help fix the crash :( As the error report says, please include the file mentioned above. That should give a bit more info about the crash.

But just by looking at this file, it seems that one of your thermal expansion machines has glitched badly, and this is crashing the game... Do you remeber placing down a thermal expansion machine right before the crash?
