Thank you! If i'd known that it was that easy ... But Forge doesn't work with mineshafter as i can see... ¿or it does?

Yeah, the black screen, that's my problem, but i've erased the META-INF folder and it's still the same, looking at the .txt i found this: 2012-12-10 19:30:22 [iNFO] [ForgeModLoader] Forge Mod Loader version 4.5.17.479 for Minecraft 1.4.5 loading 2012-12-10 19:30:22 [FINEST] [ForgeModLoader] All core mods are successfully located 2012-12-10 19:30:22 [FINEST] [ForgeModLoader] Discovering coremods 2012-12-10 19:30:22 [FINEST] [ForgeModLoader] Found library file argo-2.25.jar present and correct in lib dir 2012-12-10 19:30:22 [FINEST] [ForgeModLoader] Found library file guava-12.0.1.jar present and correct in lib dir 2012-12-10 19:30:22 [FINEST] [ForgeModLoader] Found library file asm-all-4.0.jar present and correct in lib dir 2012-12-10 19:30:22 [FINEST] [ForgeModLoader] Running coremod plugins 2012-12-10 19:30:22 [FINEST] [ForgeModLoader] Running coremod plugin FMLCorePlugin 2012-12-10 19:30:22 [FINEST] [ForgeModLoader] Coremod plugin FMLCorePlugin run successfully 2012-12-10 19:30:22 [FINEST] [ForgeModLoader] Running coremod plugin FMLForgePlugin 2012-12-10 19:30:22 [FINEST] [ForgeModLoader] Coremod plugin FMLForgePlugin run successfully 2012-12-10 19:30:22 [FINEST] [ForgeModLoader] Validating minecraft 2012-12-10 19:30:23 [FINEST] [ForgeModLoader] Minecraft validated, launching... 2012-12-10 19:30:24 [iNFO] [sTDOUT] 27 achievements 2012-12-10 19:30:24 [iNFO] [sTDOUT] 208 recipes 2012-12-10 19:30:24 [iNFO] [sTDOUT] LWJGL Version: 2.4.2 2012-12-10 19:30:25 [iNFO] [sTDERR] Exception in thread "Minecraft main thread" java.lang.NoSuchFieldError: ofCustomFonts 2012-12-10 19:30:25 [iNFO] [sTDERR] at atj.getFontTexturePack(FontRenderer.java:286) 2012-12-10 19:30:25 [iNFO] [sTDERR] at atj.init(FontRenderer.java:136) 2012-12-10 19:30:25 [iNFO] [sTDERR] at atj.<init>(FontRenderer.java:119) 2012-12-10 19:30:25 [iNFO] [sTDERR] at net.minecraft.client.Minecraft.a(Minecraft.java:422) 2012-12-10 19:30:25 [iNFO] [sTDERR] at net.minecraft.client.Minecraft.run(Minecraft.java:756) 2012-12-10 19:30:25 [iNFO] [sTDERR] at java.lang.Thread.run(Unknown Source) Can you help me?
