Digg icon no longer appears.

My digg icon is gone! I followed the instructions from another topic so that flock would start saving my passwords and logging on automatically. The instructions said to change the flock folder under C:\Users\Fernando\AppData\Roaming to 'flockbackup'. I did it. It erased all my passwords and deleted my bookmarks. I had to input all the passwords again and i've got my bookmarks back. But now i don't have a digg icon. Digg on the sidebar works fine, but there's no icon with the top five digg stories next to my address bar.
