nothing appear inside blender? help pls

so, i found the cause. hope this helps someone in the future. It was in the settings, with the blender directory, which also led me to realize that I didn't have blender 2.70 installed. I had been using sims 4 studio for so long that I couldn't even remember the right version of blender to use. Now I formatted my pc and had to remember everything again. so if you have the same problem, remember to keep the correct directory for blender, and to use 2.70.
