Site Stats is not Working

I recently switched over to .org from wordpress.com. I installed WordPress.com Stats and included in the API Key. However, my stats are showing i received 0 hits, this is definitely incorrect because I was receiving close to 300 hits daily.

This is my blog – http://www.dreamersevents.com/blog . I’ve been trying to fix this for over two months. Would anyone be able to provide some suggestions/advice as to how i can fix this.
