I have MC 1.7.4 But tekkit is still using 1.5.2 in Tekkit Posted December 12, 2013 There is no solution. You're supposed to leave it. Tekkit is supposed to Minecraft 1.5.2.[/quote Thanks, I was thinking it was that but wasn't sure. I have been having a problem with industrial craft not working so I was thinking that might've been it.
