I must have tried to fix this about 30 times with fresh installs. I will tell from the beginning. i have checked very good that the modloader i use and forge is the right version for 1.2.5. after i have innstalled modloader and deleted the META-inf i start up minecraft and it works, BUT after that i have kopied inn the forge files with winrar i start up and it goes to log in and when i have done that it just stops at updating and hangs there forever.
PLEASE HELP ME!
AAAAND efter help in the general discussion i took a fresh innstall and only deleted the Meta-inf and kopied inn the forge files, BUT KEEPS HAPPENING
