ok so i want to download fly mod for singleplayer right?

i follow every instruction to the letter on the video

i open up mincraft

hit login

go to multiplayer hit connect

my game says logging in

then flashes black and shuts down minecraft?

wth is going on i am now back to no modpack and its still doing it

i tried redownloading the minecraft launcher and that didnt fix it im getting very frustrated here

plz help

Oh Mikel type %appdata% and delete your Whole .Minecraft Folder. it should fix it,

that worked for me cause it happened to me a few times

Delete META-INF folder inside the minecraft.jar

Or just teamview some1 if u dont no how... Trust me saves a lot of wasted time...

ok i got it fixed i think i was using a wrong 1.4 i think i was using 1.4 instead of 1.4_1 /lock please
