[1.4.7] Forge + Magic Launcher

[Victouffe]

I'm running minecraft 1.4.7 with the Magic Launcher. I'm trying to add Forge (build 497) and it gives me :

Can someone help me?

Typically this means that you have installed a version of forge for the wrong version of minecraft such as installing forge for 1.4.7 on snapshots, or 1.3.2
