Not sure what version you updated from. I too have version 31, and the refresh button is located to the right of the URL box - the area that shows what web address you're looking at right now. It's a clock-wise curl.
You can always use the F-5 button on your keyboard to refresh as well. If you're using a laptop, the F-5 refresh might require holding the Function key down first...
