Query: constantly crashes on windows XP

Like another reviewer, I also liked this product, especially its ease of use, and the speed with which you could change your floorplan. But when I got an XP it crashed all the time. To add to the frustration, there is no support from their website for this product. I couldn't even find the product on the site. So I can only recommend it if you have an, apparently older computer. It worked fine using windows 98, but got slower and slower as my plans got more complicated. When I went to windows XP which I though would help, it became useless.
