What version of Minecraft forge does it require(minimum) It should tell you on the forum page for the mod. Then go here (http://minecraftforge.net/forum/index.php/topic,5.0.html) and download the corresponding Build of Forge or newer (recommended)

you can still have a 2x2, just 4x4 pixels if you know what I'm trying to explain.

I have 37 mods installed currently with forge build #152 (3.3.8.152) I believe the problem resides in the industrialcraft2 add-on's; however, I am not sure. Could someone take a look at my error message: 37 mods loaded Optifine OptiFine_1.2.5_HD_S_AA_A7 Minecraft Forge 3.3.8.152 FML v2.2.78.153 Forge Mod Loader version 2.2.78.153 for Minecraft 1.2.5 mod_CodeChickenCore : Initialized (minecraft.jar) mod_MinecraftForge : Initialized (minecraft.jar) mod_NotEnoughItems : Initialized (minecraft.jar) mod_IC2 : Initialized (industrialcraft-2-client_1.95b.jar) mod_AdvancedMachines : Initialized (AdvancedMachinesClient v1) mod_AdvancedMachines : Pre-initialized (AdvancedMachinesClient v1) mod_BuildCraftCore : Pre-initialized (buildcraft-client-A-core-2) mod_BuildCraftCore : Pre-initialized (buildcraft-client-A-core-2) mod_BuildCraftBuilders : Pre-initialized (buildcraft-client-B-builders-2) mod_BuildCraftBuilders : Pre-initialized (buildcraft-client-B-builders-2) mod_BuildCraftEnergy : Pre-initialized (buildcraft-client-B-energy-2) mod_BuildCraftEnergy : Pre-initialized (buildcraft-client-B-energy-2) mod_BuildCraftFactory : Pre-initialized (buildcraft-client-B-factory-2) mod_BuildCraftFactory : Pre-initialized (buildcraft-client-B-factory-2) mod_BuildCraftTransport : Pre-initialized (buildcraft-client-B-transport-2) mod_BuildCraftTransport : Pre-initialized (buildcraft-client-B-transport-2) mod_RedPowerWorld : Pre-initialized (RedPowerWorld-2) mod_Forestry : Pre-initialized (forestry-client-A-1.4.8.4_bc2.2.jar) mod_InvTweaks : Pre-initialized (InvTweaks-1 Client) mod_InvTweaks : Pre-initialized (InvTweaks-1 Client) mod_CompactSolars : Pre-initialized (mod_compactsolars-client-2) mod_CompactSolars : Pre-initialized (mod_compactsolars-client-2) mod_IronChest : Pre-initialized (ironchest) mod_IronChest : Pre-initialized (ironchest) mod_RedPowerControl : Pre-initialized (RedPowerControl-2) mod_RedPowerControl : Pre-initialized (RedPowerControl-2) mod_RedPowerCore : Pre-initialized (RedPowerCore-2) mod_RedPowerCore : Pre-initialized (RedPowerCore-2) mod_RedPowerLighting : Pre-initialized (RedPowerLighting-2) mod_RedPowerLighting : Pre-initialized (RedPowerLighting-2) mod_RedPowerLogic : Pre-initialized (RedPowerLogic-2) mod_RedPowerLogic : Pre-initialized (RedPowerLogic-2) mod_RedPowerMachine : Pre-initialized (RedPowerMachine-2) mod_RedPowerMachine : Pre-initialized (RedPowerMachine-2) mod_RedPowerWiring : Pre-initialized (RedPowerWiring-2) mod_RedPowerWiring : Pre-initialized (RedPowerWiring-2) mod_RedPowerWorld : Pre-initialized (RedPowerWorld-2) Minecraft has crashed! ---------------------- Minecraft has stopped running because it encountered a problem. --- BEGIN ERROR REPORT 13fc056a -------- Generated 7/17/12 8:37 PM Minecraft: Minecraft 1.2.5 OS: Windows 7 (x86) version 6.1 Java: 1.7.0_05, Oracle Corporation VM: Java HotSpot Client VM (mixed mode), Oracle Corporation LWJGL: 2.4.2 OpenGL: ATI Radeon HD 2600 XT version 3.3.11653 Compatibility Profile Context, ATI Technologies Inc. java.lang.IllegalArgumentException: Slot 188 is already occupied by ic2.advMachine.BlockAdvMachine@1fd422c when adding ic2.advMachine.BlockAdvMachine@382ce at pb.<init>(Block.java:251) at agy.<init>(BlockContainer.java:7) at ic2.advMachine.BlockAdvMachine.<init>(BlockAdvMachine.java:25) at mod_AdvancedMachines.load(mod_AdvancedMachines.java:51) at cpw.mods.fml.common.modloader.ModLoaderModContainer.init(ModLoaderModContainer.java:351) at cpw.mods.fml.common.Loader.modInit(Loader.java:263) at cpw.mods.fml.common.Loader.initializeMods(Loader.java:604) at cpw.mods.fml.client.FMLClientHandler.onLoadComplete(FMLClientHandler.java:203) at net.minecraft.client.Minecraft.a(Minecraft.java:426) at net.minecraft.client.Minecraft.run(Minecraft.java:735) at java.lang.Thread.run(Unknown Source) --- END ERROR REPORT 9e0c8fa3 ---------- Thank you for taking the time to look it over. -stealthycow
