In my experience, GL error 1281 is caused by textures dimensions that are non-power-of-two. I'm not sure if it applies to this situation, but might work checking out the OpenGL extension viewer at http://www.realtech-vr.com/glview/download.php to confirm your graphic card's supports that GL extension. (Look for GL_ARB_texture_non_power_of_two.) You can also update LWJGL and use the lwjgl_debug.jar in place of the lwjgl.jar to provide debug information which might help you track down the cause. Why this happens because of Forge, I can't say...

356+ is for MC 1.4.3. Stick with 355.

Looks like a missing GuiAPI to me.

I see no reason to think that any 1.4.2 mod should work with 1.4.3.

Strange. What a bad API. You get a similar error if you extract the .jar, which is why I thought that's what you did.

You extracted the .jar didn't you? tsk, tsk. Just put the .jar in your mods directory.

Build #355 works fine for me with Magic Launcher 1.0.0 -- I'm on Windows, tho, not Linux. You sure that's a clean .jar?

Creepy Pasta Craft goes in the .jar and overwrites sq.class..

Might need to be multimc or java you need to let through.. As the error says, to install them manually, copy those three files into your minecraft/lib folder.

Try copying all files from Forge into the jar. Also make sure you are using the right version.

There's a post at the top of this forum... called "Excessively Asked Questions: Read me before posting!" Start there. Hint: 2012-10-29 20:39:23 [sEVERE] [ForgeModLoader] There were errors during initial FML setup. Some files failed to download or were otherwise corrupted. You will need to manually obtain the following files from these download links and ensure your lib directory is clean. 2012-10-29 20:39:23 [sEVERE] [ForgeModLoader] *** Download http://files.minecraftforge.net/fmllibs/argo-2.25.jar 2012-10-29 20:39:23 [sEVERE] [ForgeModLoader] *** Download http://files.minecraftforge.net/fmllibs/guava-12.0.1.jar 2012-10-29 20:39:23 [sEVERE] [ForgeModLoader] *** Download http://files.minecraftforge.net/fmllibs/asm-all-4.0.jar Make sure your firewall lets Minecraft out.

It may be worth noting that AutoSwitch works with Forge build #338 and earlier.

duckbutter keeps messing up by putting the mod into his minecraft.jar instead of putting the .zip into the mods folder where it belongs.

Ah, it was worth a shot. Sorry! I am curious to know what causes this, since now it is even more mysterious to me..

I've toyed with MCP for maybe 5 minutes, so I'm not positive. It would be whatever the development equivalent of the normal .minecraft/config/ directory is (where all the mods store their config files)

Try deleting files out of the config/ directory that eclipse is using. I ran into this after adding/removing a number of mods in my hoarding environment... not quite sure what causes it, but once I cleared out my config directory, it went away..

Downgrade to Forge #338 - it works there. Doesn't work with #339 or later..

Update to Java 7. Possibly update your sound card drivers as well.

Optifine should be at the bottom of the list.

#339 and Optifine (U_A7) work for me.

Step 1: Read Step 2: Think

Both PixelMon and CC are trying to use the same block ID. Change the config file or get ID Resolver.

Read the MystCraft requirements. Or the MystCraft filename (mystcraft-uni-1.3.2-0.9.2.00-Forge-4.0.0.247.zip). The current version of MystCraft requires you to use Forge 4.0.0.247.

From terrafirmacraft.com: Install the latest Forge Universal into your jar file. Must use 4.1.2.269+ Install PlayerAPI Place TFCraft_Universal into your Minecraft mods folder after installing the prerequisites. Be Awesome! I do not see PlayerAPI in your setup.
