Black screen when clicking on Flats

Hi, I was building in one of the Culpepper House Flats in San Myshuno when all of a sudden, I had red screen of death. It then turned black and all I could see was the mouse.

I then restarted the game and now whenever I click on Culpepper House it comes up with a black square.. I've managed to move my sim out but still can't access these flats - please help me!!! ):

I've removed mods and pressed 'repair game' through origin, nothing seems to be working. 

Thanks for your help!
