Importing Mesh Forever {Solved}

I'm trying to make an override for the world's grass, i don't like that "paper like" looking, so i downloaded a mesh, put it into a mesh that i exported from an EA object, changed the cut values and tried importing, but it simply doesn't import, keeps loading forever. I checked in task manager and the Blender process is using ~30% of the CPU, and if i close it, Sims4Studio returns this error:

Sorry, i'm new doing this, but already made some Digimon dolls. Do i have to change more things on Blender, plus the cut value?
The grass mesh that i downloaded came with no texture (.3DS format), may this be the problem? I was planning on using any green image, the texture is not very important.
Or is the mesh too big (5,57mb)?
