Hi all My daughter updated minecraft to 1.6.2 I tried installing the latest version of forge by copying the files into the .bin file and the game wouldn't load. silly me forgot to make a back up so had to delete the jar file. When the game reopened there is now no longer a jar file it is now called launcher. When I try to copy the files over now it pops up the box asking me to overwrite or re name the files and freezes. Can't click any options. If I use the TAB key I can highlight overwrite and press enter at which point it tells me it can't find the destination. Minecraft is shut down when I attempt this. I have also deleted the meta.inf file and I still get the same problem. If you have any ideas I would be very grateful. Thanks
