When you were using the 1.4.6 forge, you were trying to use a PortalGun version that needed a newer Forge version. 2013-02-19 13:33:14 [ForgeModLoader] MinecraftForge v6.5.0.467 Initialized 2013-02-19 13:33:16 [FINE] [ForgeModLoader] PortalGun(Portal Gun:1.4.7.4): PortalGun1.4.7v4.zip (required-after:Forge@[6.5.0.483,))

...no 497 is the recommended, not the latest. "Update" means "get the latest".

Lex, I just noticed that bcprov-jdk15on-147.jar isn't in the fml_libs.zip. Should it be added? James: Download http://files.minecraftforge.net/fmllibs/bcprov-jdk15on-147.jar and put it in your lib folder too.

Post an updated log. If you removed the Coremods folder, it will be a different error this time.

Probably inside "Kes5219ImprovedFirstPerson1.4.7R1_U1.jar" in your Coremods folder.

It means the minecraft.jar that you installed FML into is version 12w50a, not 1.4.7 as FML is expecting. To fix it, delete minecraft.jar and have the launcher re-download it, then re-install Forge.

You are supposed to read the EAQ because it tells you exactly how to fix the issue you are having. java.lang.ClassNotFoundException: com/google/common/collect/MultiMap; java.lang.NoClassDefFoundError: com/google/common/io/LineProcessor; ]java.lang.RuntimeException: A download error occured: Download this: http://files.minecraftforge.net/fmllibs/fml_libs.zip and extract to /lib in your .minecraft folder.

2013-02-10 14:27:56 [sEVERE] [ForgeModLoader] This version of FML is built for Minecraft 1.4.7, we have detected Minecraft 12w50a in your minecraft jar file 2013-02-10 14:27:56 [sTDOUT] A CRITICAL PROBLEM OCCURED INITIALIZING MINECRAFT - LIKELY YOU HAVE AN INCORRECT VERSION FOR THIS FML

In the config folder. %appdata%/.minecraft/config

Delete your forge.cfg, something is wrong with it. A new one will be created when you load the game after you delete the existing one.

The fact that it can freeze and crash means it's opening. "Opening" does not mean "Gets to main menu" it means the window opens. Check the folder.

When you run MineCraft with Forge installed, it creates a ForgeModLoader-Client.0.log in the %appdata%/.minecraft directory. Post that here =)

You know, uyjulian, it's really annoying when you do that. zaneoblaeno, it looks like java ran out of memory while trying to do stuff. You can change how much memory to allocate to minecraft. If you're using a launcher, there's usually settings in it. Otherwise, there is a command line parameter you can use. I don't know it off the top of my head, but you can probably find it pretty easily by searching either these forums, or good.

4087 is already occupied by co.uk.flansmods.common.BlockPlaneWorkbench Block ID 4087 used by Flan's Mod for the BlockPlaneWorkbench Go to %appdata%\.minecraft\config and open FlansMod.cfg Change the "Blocks" area to something that is unused, these are the values I use: block { I:"Crafting Table"=652 I:"Gun Box"=650 I:"Team Spawner"=651 }

Don't use ModLoader methods

Don't use RedPower's autoassign feature, reassign the IDs yourself. I mapped out ranges of IDs for my mods ahead of time so I know nothing will conflict.

cpw just fixed a crash in build 511. Upgrade Forge and see if it's fixed. If not, post your ForgeModLoader-Client.0.log file

That's not the right log, but I see you're running build 510. cpw just fixed a crash in build 511. Upgrade Forge and see if it's fixed. If not, post your ForgeModLoader-Client.0.log file

I think cpw just fixed that in build 511. Upgrade Forge and see if it's fixed.

Inventory Tweaks, Back Tools, maybe Mob Dismemberment. Check to see if these are client-side only mods

No. "Caused by: java.lang.RuntimeException: Attempted to load class ayp for invalid side SERVER" He's trying to load a client-side mod on a server. My first guess is Rei's Minimap.
