I have a house that I have been working on for 2-3 months. It is for a contest. I had no trouble until I moved a couple in to test the utility of the house. It played fine everything was working great, that was last night.
Today I opened the game and tried to get into the house but the games crashed and terminated. I removed the couple. I opened the Clean Installer and tided up the downloads. I took out all downloads for the past 3 days. 
Still crashing. I removed all meshes and hacks. 
Still crashing. I took Half of my downloads out of the Sims 2 folder. 
Still crashing. I took everything, 
everything out of my download folder. 
I deleted cig-macallit and accessories. 
I did a hack conflict scan. 
I put the house into the houses and lots bin, created a brand new empty world and pulled the house out of the bin and placed it in the new neighborhood. 
The game still crashed when I try to enter the lot. 
These are my game specs:

I was going to remove all the houses I have downloaded in the last 2 weeks and put them in the trashcan.
Should I also trash the house and start from scratch? Or is there hope to save it?
Thanks from Nonni
