locksmithmusic on "My StumbleUpon Isn't Working Properly"

It was working just fine earlier. For instance, I would visit a blog post I made my own WordPress blog & click the StumbleUpon button & it would go through. Now my URLs aren't being posted. It goes from looking like this: http://polo67life.com/2009/08/30/deal-breakers-beat/

To looking like this: http://www.stumbleupon.com/submit?url=http%3A%2F%2Fpolo67life.com%2F2009%2F08%2F30%2Fdeal-breakers-beat%2F&title=The+Making+of+%22Deal+Breakers%22+Pt.+2+%26amp%3B+3

Then it just freezes on a blank/white screen with the above link in the URL browser. Somebody please help. Thanks in advance. 88-Keys of Locksmith Music, LLC
