...after downloading the required items first, and the game crashes at 5%...

What might those "required items" have been? Spit MK.I, by itself, should not cause a 5% crash.
The 5% crash is usually a missing or corrupt .SFS file. It can happen if you install a sound mod, mod activator, or unified installer, without first patching the game to 4.08m. You'll have to provide more precise details about what you downloaded, or installed, or did.
