I looked at others with similar titles, but could not find any solutions. Basically, I deleted META-INF then after that put the Forge 1.5.2 files into the minecraft.jar. Then I ran it, and it seemed to be doing something and it loaded and stuff, but then after it said it was launching, it just stayed on the black screen, never went to the Mojang logo.
Here's the log- http://pastebin.com/e0363zkb
Thanks for your time!
Edit-Also, I'm just running on vanilla atm, no mods or anything (besides forge).
