I just tried to download this whole thing last night and every time I put my login and stuff it tells me it could be wrong please try again. and I don't even know how to do the whole server thing so ya if someone could walk me through it or something cause I followed all the directions and such.If you could help this would  be great because my brother told me about this and I played a bunch on his singleplayer on his mac so I wanted it on my windows and its not working  even though yes i used my minecraft account  not my World of Minecraft even  though they are both the same.....
