Whenever I try and press "play" on a modpack the loading bar will appear on the bottom, but when it gets to 100% nothing happens. I'm sure it's something I'm doing but I'm new to modepacks and couldn't find a better forums to post it on.

how?

Whenever I try and open tekkit classic it starts to load and then I get the fallowing crash report: Mods loaded: 29 ModLoader 1.2.5 mod_CodeChickenCore 0.5.2 mod_ModLoaderMp 1.2.5v1 mod_MinecraftForge 3.1.2.90 mod_NotEnoughItems 1.2.2 mod_ReiMinimap v3.0_04 [1.2.5] mod_BuildCraftCore 2.2.14 mod_BuildCraftBuilders 2.2.14 mod_BuildCraftEnergy 2.2.14 mod_BuildCraftFactory 2.2.14 mod_BuildCraftTransport 2.2.14 mod_ComputerCraft 1.33 mod_CCTurtle 1.33 mod_EE 1.4.4.0 mod_EnderStorage 1.1.1 mod_IC2 v1.95 mod_InvTweaks 1.41b (1.2.4) mod_Railcraft 5.0.3 mod_RedPowerControl 2.0pr5b1 mod_RedPowerCore 2.0pr5b1 mod_RedPowerLighting 2.0pr5b1 mod_RedPowerLogic 2.0pr5b1 mod_RedPowerMachine 2.0pr5b1 mod_RedPowerWiring 2.0pr5b1 mod_RedPowerWorld 2.0pr5b1 Balkon's WeaponMod 1.2.5 v8.6.0 mod_WirelessRedstoneCore 1.2.0 mod_WirelessRedstoneRedPower 1.2.0 mod_WirelessRedstoneAddons 1.2.0 Minecraft has crashed! ---------------------- Minecraft has stopped running because it encountered a problem. --- BEGIN ERROR REPORT c148a767 -------- Generated 6/28/14 8:08 AM Minecraft: Minecraft 1.2.5 OS: Windows 8 (x86) version 6.2 Java: 1.7.0_55, Oracle Corporation VM: Java HotSpot Client VM (mixed mode), Oracle Corporation LWJGL: 2.9.0 OpenGL: Intel® HD Graphics 4600 version 4.0.0 - Build 9.18.10.3324, Intel java.lang.IllegalArgumentException: Slot 207 is already occupied by dan200.computer.shared.BlockComputer@10e24d7 when adding railcraft.common.rails.BlockRailElevator@194ae28 at pb.<init>(Block.java:249) at pb.<init>(Block.java:281) at railcraft.common.rails.BlockRailElevator.<init>(BlockRailElevator.java:74) at railcraft.common.RailcraftBlocks.registerBlockRailElevator(RailcraftBlocks.java:75) at railcraft.common.modules.ModuleExtras.initializeModule(ModuleExtras.java:29) at railcraft.common.modules.RailcraftModuleManager.initializeModule(RailcraftModuleManager.java:140) at railcraft.common.modules.RailcraftModuleManager.loadModules(RailcraftModuleManager.java:71) at mod_Railcraft.load(mod_Railcraft.java:52) at ModLoader.init(ModLoader.java:891) at ModLoader.addAllRenderers(ModLoader.java:189) at ahu.<init>(ahu.java:77) at ahu.<clinit>(ahu.java:8) at net.minecraft.client.Minecraft.a(Minecraft.java:394) at net.minecraft.client.Minecraft.run(Minecraft.java:732) at java.lang.Thread.run(Unknown Source) --- END ERROR REPORT 7a8734a2 ---------- I have tried re-downloading the pack the launcher and even from different browsers, this is my favorite pack so if anyone has any ideas i'm all ears.
