PREZI is amazing!! But I can't find the Old 'Style' that blown me away...

Prezi is just amazing!!! I am an economist, and this my first time using Prezi. Few days ago, I created my first presentation using Prezi. I stayed with the default 'Style', which I love it so much. To keep the story short, I was exploring Prezi and happened to click on other 'Style', but now I couldn't get back to the default style (dark blue/ black background, Red and Orange color words) that ablosutely BLOWN me away... Is there a way that you can help me to get back to the previous 'Style' (it's not available on preset style now) please? I have a downloaded version with the 'Style' that I like, but there are some typos in this version :( I trully appreciate you help on this!!
