FlyingManatee

Alright! Found the problem(Well,not actually but I solved it!).Might have to try to solve it myself on 1.7.2 and 1.6.4 though as most mods are on those versions...Still,thanks!

Well that is awkward...

I am very sure I used the right installer. I really do not know why it would say I have another version.

Umm forge is latest is there an update that doesn't show on the files page?I mean I used installer for 10.13.1.1217
