Tough dry stew meat.. help!?

I am making beef stew and I am using Paula Deens recipe (a href="http://www.foodnetwork.com/recipes/paula-deen/old-time-beef-stew-recipe/index.html)." rel="nofollow"http://www.foodnetwork.com/recipes/paula…/a I browned the beef first then followed all directions. It has been 2 hours and I tasted the beef and it is dry and tough. It has liquid covering it still and it has been on low for two hours. Any suggestions on how to save my meal?
