That usually means that a too old of version of forge is being run, have you updated?  You gave no information of what was installed, what versions, etc...

laxmanos has been on this problem on the old forums with someone else and it doesn't look like they came to a conclusion. there is no error generated by mod loader. I used a clean install of MC 1.2.5 with only mod loader. It works with modloader but after extracting forge 94 the screen gets stuck on "done loading" screen. this  only happens to some people. i tried using my laptop to get it working and i encountered the same problem. i think there is only one thing similar between my desktop and my  laptop is Windows 7 Untimate 64.

1.2.5 is no longer supported on this forum.

Please update to a modern version of Minecraft for support.

edit: i accidentally pressed last page and bumped this
