Solved! So becouse the Force update is updates to 1.3.1, I downloaded 1.2.5 jar from a 3rd party website and the jar was not clean! Now I downloaded it from an other website and now it's works!

No, like I said before, I tried it without any mods, only with forge.

Ok, now I delete all the mods from the mods folder and I only add the forge 3.3.7.136 and I get the same error. The jar was clean before I put the forge in it. I need 1.2.5 becouse I'm using MCPC build on the server and its mods only available for 1.2.5.

Ok, I took it out, but I get the same error I load the world, or join a server and after a few seconds the Minecraft crashes with the error

Is the Forge already contains it?

Hi! I'm trying to put some mods to Minecraft 1.2.5, but when I load a Singleplayer map or join a same modded Minecraft server the Minecraft crashes and I get this error: 9 mods loaded Minecraft Forge 3.3.7.136 FML v2.2.48.135 Forge Mod Loader version 2.2.48.135 for Minecraft 1.2.5 mod_MinecraftForge : Available (minecraft.jar) mod_ModLoaderMp : Available (minecraft.jar) mod_mocreatures : Available (DrZharks MoCreatures Mod v3.7.1.zip) mod_DungeonPack : Available (DungeonPack 1.2.5 v6 Client.zip) mod_AnimalBikes : Available (forge animalbikes client 1.2.5 v2.zip) mod_HotAirBalloons : Available (Hot Air Balloons - MP Client - 1.2.5 - v2.1.zip) ClassCraft : Available (Jimmynator_client_2.4.zip) mod_MorePistons : Available (More Pistons v1.0.zip) mod_SmartMoving : Available (Smart Moving Client for ModLoader.zip) Minecraft has crashed! ---------------------- Minecraft has stopped running because it encountered a problem. --- BEGIN ERROR REPORT 3b12dba1 -------- Generated 2012.09.08. 12:14 Minecraft: Minecraft 1.2.5 OS: Windows 7 (amd64) version 6.1 Java: 1.7.0_06, Oracle Corporation VM: Java HotSpot 64-Bit Server VM (mixed mode), Oracle Corporation LWJGL: 2.4.2 OpenGL: AMD Radeon HD 6800 Series version 4.2.11733 Compatibility Profile Context, ATI Technologies Inc. java.lang.NoSuchFieldError: isSubWorld at rt.<init>(EntityFX.java:40) at ky.<init>(SourceFile:10) at l.b(RenderGlobal.java:1873) at l.a(RenderGlobal.java:1820) at .a(World.java:1514) at agv.b(BlockFluid.java:431) at .v(World.java:3671) at net.minecraft.client.Minecraft.k(Minecraft.java:1880) at net.minecraft.client.Minecraft.x(Minecraft.java:822) at net.minecraft.client.Minecraft.run(Minecraft.java:750) at java.lang.Thread.run(Unknown Source) --- END ERROR REPORT f449425b ---------- Anybody knows what is the problem?
