New Mesh Won't Show Up on S4S?

I'm not really sure what to call this problem? I have been fighting this issue for a few days (try a few things, get annoyed, walk away, come back, try a few things, get annoyed, repeat...)

So, what's happening is I'm trying to import my new mesh to S4S and the preview still shows the original item and not my new one? And when it finally seems like it's trying to load my mesh, it never stops "importing". I have tried lowering my poly, decimate geo, smooth shade, double check my cut number with the original, and I'm ready to throw my computer out the window.

I can import my new texture though, so no problems there. I'm only struggling with getting this dang mesh imported. Somebody please help before I give up entirely

I have inlcuded a few photos of the loading screen, cut settings, and subsurf settings. Let me know what else you may need! :D
