According to a blog post on the DIY Network website:
"...Various issues have prevented us from closing on the house and being in a position to award it to a winner. DIY Network no longer has any affiliation with the developer, nor are we involved with the developer's apparent efforts to sell the 2009 Blog Cabin."
Youch, that sounds like some nasty discussions were going on behind the scenes.
But, don't worry, your entry time is not lost! DIY has changed their grand prize to $500,000 cash. That should let you purchase your own dream cabin, or you could put that big cash prize toward whatever other kind of purchase you'd like.
Let's keep our fingers crossed that DIY brings this fantastic sweepstakes back next year, despite the difficulties this year.
