Hey!
I've read a few topics and they all suggest to install this yourself.
I tried adding it to the mods folder, but that makes Tekkit crash when I press 'play'.
I also tried to update forge (downloading a newer version and putting it in the folder where the old forge is) but that doesn't work either.
Am I doing the 'update forge' thing wrong, or something else?
Help would be very appreciated
Edit: To be specific, on this site: http://files.minecraftforge.net/
I tried to install 1.6.4 and 1.7.4 recommend builds, specifically 'universal'
