Noting I've tried has worked. Someone Please Help Me!!!!!!
If you use File > Open and select the .ai file, it will open as a "Photoshop PDF" and you will get a dialog with a default resolution of 300 ppi to rasterize it.
You can input 600 any any resolution you want and it will rasterize it preserving the details.
This is for a flat ai file.
If you want to import a layered ai file and preserve everything, you can save it as a psd in FireWorks.
