I did and I'm having a hard time understanding what is wrong. I don't get a sweet home 3d will now close message at all and I can't find the properties option.

It's very strange , every time I try do anything to my fairly simple models ( I haven't even added textures, just doors and windows so far)
the program crashes.

I have no idea what's causing this. Can someone please help?

I keep getting this:
