nothing seems to work, always the building terrain error, no matter which version for 1.4.7 i try, maybe i'll figure out my problem someday.

i always press file>select all and then drag it into the new folder if this isn't the correct way to do it tell me how please.

so i tried to open the world again, same error, so i removed the jar file and tried installing forge again for a solid 4-5 times and i keep getting the exact same error.

i installed the reccomended forge for 1.4.7, i have no mods installed at all. i delete meta.inf first and then copy the whole zip into minecraft.jar but nothing seems to work. i'm obviously doing something wrong but i'm too dumb to notice what it is. ForgeModLoader-client-0.log
