No I don't use arabic text. I've managed to solve my problems though, my development environment was setup correctly by forge. I just reinstalled it and now it works.

I haven't edited any main classes, I created my own!

This is my first attempt at trying to create a mod. I've made a very simple mod that adds one block. Eclipse showed no errors so I tried to run it. It loaded until the 'mojang screen' and then crashes with the following error: 6:52:00] [main/INFO]: Loading tweak class name cpw.mods.fml.common.launcher.FMLTweaker [16:52:00] [main/INFO]: Using primary tweak class name cpw.mods.fml.common.launcher.FMLTweaker [16:52:00] [main/INFO]: Calling tweak class cpw.mods.fml.common.launcher.FMLTweaker [16:52:00] [main/INFO]: Forge Mod Loader version 7.2.116.1024 for Minecraft 1.7.2 loading [16:52:00] [main/INFO]: Java is Java HotSpot(TM) 64-Bit Server VM, version 1.7.0_25, running on Windows 7:amd64:6.1, installed at C:\Program Files\Java\jre7 [16:52:00] [main/INFO]: Managed to load a deobfuscated Minecraft name- we are in a deobfuscated environment.
