I Found a mod pack that is 1.2.5 and I want to play it on multiplier. I have tried getting a 1.2.5 server and putting Forge in it but it doesn't work (I know the mod pack has Forge). So I was wondering if there was a way to take the Tekkit server and change it to this other Mod Pack. This would really help if I could get an answer.
