Custom Google Search not working

I had installed the google custom search on my website - few months back and until recently all was working fine. Just today when i checked back, the search was not working. It keeps saying 'loading...' but nothing turns up really.

i am not sure how an already configured site is not working without any changes done. i have entered the searchID on the site and chosen Display search results as: Search Results, style - minimilist, Theme for popup-flickr. Plz. help me with this issue. Thank you!
