I have some good news. I found a backup folder of the Whitevale region on an old DVD hiding deep in the darkness of one of my drawers in my room. The only problem is, the folder is outdated about 4 or 5 months... So I would have to rebuild tons of stuff which will take some time. If I ever have the time, I might do it, but I have already started a new region and I am going to stick mostly to that for some time.
Here is a picture of the region in it's current state. It has about 7,000 people which is about a third of the size it was at the time my PC died.
