I know this is for Tekkit Classic, but I could'nt find a subject where custom modpack glitches were. Whenever I try to get a custom modpack, I do everything right (URL and shit) and stuff goes smoothly until I start a world. I start it in creative to look at what items there are, but none of the custom content is in the creative menu. Help?

I have tried EVERYTHING but I cannot make a tekkit lite or a tekkit server. Can someone tell me how or tell me a video that actually works without hamachi? I run windows 8 and it is hard.
