Same here. Win 7 Pro 32-Bit. I had literally just clicked the link to buy a license and decided to grab the new update as long as I was at the site since Ludum Dare is coming up soon. <img src="smileys/smiley13.gif" border="0" align="middle" />
Looking forward to the fix. 
Ashley, do you know what release I should downgrade to until this is fixed?
