Here's the official word from Ubi:
"The Ubisoft Labor Day promotion for US residents only making the PC games Prince of Persia: Sands of Time, Far Cry, and Rayman Raving Rabbids available for ad-supported freeplay has now closed. Thank you for your interest in the program. For more information about these and other Ubisoft titles, please visit *www.ubi.com."
which means Ubisoft has closed the free games promotion for the time being. If you haven't already activated your free game install, it won't work. We'll have more news on these games if and when they become available again!
