New Super Mario Bros Wii Level Problems

[PianoDude1011]

I can't seem to be able to enter a certain level in my New Super Mario Bros. Wii (5-4, to be more exact). After entering the pipe in the beginning of the level, Dolphin goes black and goes to 0 FPS (according to the top anyway, the blue FPS count stays the same, and the VPS seems to be unaffected). It's not a corrupt ISO, I used CleanRip to rip the ISO from my disc, and if CleanRip comes across a corrupted part of the disc, it stops copying and an error message shows. I'm using Dolphin 4.0-1516 and a Lenovo G505s (link: http://www.newegg.com/Product/Product.aspx?Item=N82E16834313719). My laptop has 8GB of RAM, but otherwise the specs are the same. Anyone know why this is happening?
EDIT: It's not just that level, it's every level that does this :/

Do you have EFB-2-RAM enabled? It´s required for that game.

I thought EFB to ram was only necessary to see the spinning/blue coins. I played through the entire game with EFB to texture.
