Forge 1.8 Crash on Startup

[Esky]

Hello! I've been trying to install Forge from the link here - http://files.minecraftforge.net/fml//1.8 - And have been running into some issues. I ran the .exe from that site, launched Minecraft and set a new profile to use the new version-thing the executable created. At first, things look fine (at least to me):

 

 

but then I get a crash report - http://pastebin.com/igtitSem . I'm just trying to install Forge here, following this tutorial Google gave me - http://tacticallion.com/shaders-mod/ . my mods folder is empty at the moment (though I plan on installing some shaders when this is working, which is what I set out to do in the first place). I have previously been using Optifine, though I'm not using the profile that came with and I can't find anything in my .minecraft that looks like it belongs to that - I haven't touched my game in such a long time that I forget what the Optifine installation process involves, so I might be missing something. Any help you can give will be greatly appreciated (I hope I did this right!)
