I've been trying to learn how to mod for minecraft, so I watched a tutorial on how to do so while following exact instructions. I get to the end of the tutorial, and I go to launch the mod for the first time (in eclipse, should have mentioned), and I get the following error as it refuses to launch forge: Sep 10, 2014 1:09:49 PM net.minecraft.launchwrapper.LogWrapper log INFO: Loading tweak class name cpw.mods.fml.common.launcher.FMLTweaker Sep 10, 2014 1:09:49 PM net.minecraft.launchwrapper.LogWrapper log INFO: Using primary tweak class name cpw.mods.fml.common.launcher.FMLTweaker Sep 10, 2014 1:09:49 PM net.minecraft.launchwrapper.LogWrapper log INFO: Calling tweak class cpw.mods.fml.common.launcher.FMLTweaker 2014-09-10 13:09:49 [iNFO] [ForgeModLoader] Forge Mod Loader version 6.4.45.953 for Minecraft 1.6.4 loading 2014-09-10 13:09:49 [iNFO] [ForgeModLoader] Java is Java HotSpot 64-Bit Server VM, version 1.8.0_20, running on Windows 7:amd64:6.1, installed at C:\Program Files\Java\jre1.8.0_20 2014-09-10 13:09:49 [iNFO] [ForgeModLoader] Managed to load a deobfuscated Minecraft name- we are in a deobfuscated environment.

I read the EAQ, and from what I'm guessing, you need an error log, I just now included that in my post, so if you want to take a look at that, there it is. Although the EAQ states that an error log is needed, its not very specific on which error log it needs, other than a name that I cannot find anywhere on my computer in general. If a different log is needed, I can provide it if you could give me a specific location on where to find it.

After starting up minecraft, I recieve the following screen as the Minecraft menu, I'm not quite sure why it does this, but I've done several things to attempt to solve the problem, such as removing mods from mod folder, removing resource packs, and even deleting minecraft and building a new .minecraft folder. All of these attempts were in vein, and I still have the same screen each time I start minecraft forge. I have listed the versions of forge I have tried, and I hope I could get either an explanation to why it does this, and/or a solution to the issue. Thank you for taking the time to read this report. 10.13.0.1194 10.13.0.1180 10.13.0.1170 After looking at the logs, it proceeds to tell me the following from start to finish: [10:59:16] [main/INFO]: Setting user: LordMucaus [10:59:22] [Client thread/INFO]: LWJGL Version: 2.9.1 [10:59:39] [Client thread/INFO]: Reloading ResourceManager: Default, FMLFileResourcePack:Forge Mod Loader, FMLFileResourcePack:Minecraft Forge, MemeSound [10:59:41] [sound Library Loader/INFO]: Sound engine started [10:59:43] [Client thread/ERROR]: ########## GL ERROR ########## [10:59:43] [Client thread/ERROR]: @ Pre startup [10:59:43] [Client thread/ERROR]: 1280: Invalid enum [10:59:46] [Client thread/INFO]: Created: 512x256 textures/blocks-atlas [10:59:48] [Client thread/INFO]: Created: 256x256 textures/items-atlas [10:59:48] [Client thread/INFO]: Reloading ResourceManager: Default, FMLFileResourcePack:Forge Mod Loader, FMLFileResourcePack:Minecraft Forge, MemeSound [10:59:49] [Client thread/INFO]: Created: 256x256 textures/items-atlas [10:59:52] [Client thread/INFO]: Created: 512x256 textures/blocks-atlas [10:59:53] [sound Library Loader/INFO]: Sound engine started [11:00:19] [Client thread/ERROR]: ########## GL ERROR ########## [11:00:19] [Client thread/ERROR]: @ Post render [11:00:19] [Client thread/ERROR]: 1286: Invalid framebuffer operation [11:00:19] [Client thread/INFO]: Stopping! I left out a large section of the log, due to the fact that the separated text above just just repeating a few hundred times.
