Good evening! I hope I'm able to help you out.
So, unfortunatelly, sometimes there is nothing the MODs or Admins can do to help you with it.
Maybe, one single mesh or item is causing you problems. The only thing is to test which of them are causing problems to you. Try first installing the objects only. If you game doesn't crash, it isn't the objects. Then delete them all and add the meshes. When the game crashes after you installing one of them, you'll see which is causing you problems, and maybe, you won't be able to have them in your game. Also, the problem may be your computer not having a fairly good drive to load the meshes. And that makes you crash. If you really want the objects/meshes to work, you can try buying a new driver or updating the one you already have. I hope I helped somehow. Good luck!
No, you wouldn't have to reinstall. You'd have to search for your drive's name and model, go to it's website (you can google it) and download a newer version of it.
Alright, good luck! If you need anything, I'll stay tuned to your thread to check if you need something else.
