It burned!!

I was so disappointed when I got home from work on Tuesday. I planned very well and started dinner in my crock pot so we could have a nice, warm, yummy dinner when we got home. Well, that didn't happen. My dinner burned. I completely followed the directions. Now I am left wondering if my crock pot is too hot or if there is some other problem. I am going to have to use it over the weekend while I am home so I can keep an eye on it. It would be a wonderful solution to busy nights after work. Please let my crock pot work!!!
