The problem is with a thermal expansion block trying to find a texture that is out of bounds for the texture array (if textures use arrays, not sure how thermal expansion is coded), which probably means there are things missing. Post the full error report like Forthewin11 said so we can see what happened, but reinstalling tekkit lite should fix the problem.
