So, I recently attempted playing Vanilla Minecraft through the Technic Pack. It should run completely like a clean .minecraft and clean minecraft.jar. However, upon installing Forge ModLoader 1.4.7/6.6.0 into 1.4.7 Vanilla minecraft.jar, I run Vanilla, the "Hello!" Forge window appears blank, then disappears within a few moments, still blank, and I am left with a crashed, white-screened window where Minecraft should be.
What's the problem here?
I don't have an error log because it never tells me anything. Just freezes indefinitely at a white screen.
