I really want this mod like really fuckin bad, it's called "Old Days Mod". Probably the best I've seen so far EXCLUDING SPC.

That's where I got it from, that's where I got the instructions from. Where I downloaded from.

When I install this with any other mod, MC crashes. Then when I try and remove that mod, MC crashes.

It ONLY works when loading the mod itself, and yes I have Modloader AND ModloaderMP and have deleted meta-inf completely. I want to use this mod with all other mods but I can't. Any help?

and thank you @Nico for deleting outside link.

Anyone? Please..

Oh come on please anyone could help me here...seriously? Clearly I need some major help right now. I've been waiting for a long time..
