Sorry for the vague reply, I'm not really sure where to find an error log to see what the problem is.
Let's start with not being able to open the OpenGL configuration in 7th Heaven. When I click it, it doesn't open anything. No matter how many times I click it, no matter how many times I delete 7th Heaven and re-download it. It's been ran as administrator, etc.
I believe it might have something to do with why the game won't launch with the mods. The game launches just fine when I run it without the mods.
I am using Windows 8, 64-bit.
My specs should be way above the required.
