I used the button on the loader, I'm now going to try it manually but I think it'll come out with the same result.
Thanks
EDIT
I just tried changing it manually and I tried to open my inventory and the game crashed, (probably NEI) going to try again
I think I'm just going to put the mods i want into my minecraft without using the Technic Launcher, there is only a few mods i want anyway so it won't be to difficult, thanks for trying to help.
