Thanks for your encouraging message
But you should know that it's still possible to earn some money from an open source free program like I try to do, to be able to spend more time on its development.
Your issue looks like a problem in the driver of your graphics card. Please have a look to the FAQ if some suggestions could help you fix it.
Note that you could also import directly furniture libraries available at import page, but you should fix your issue because it might provoke some crashes later.
