Problem with Twitter Feed

I'm experiencing issues with the Twitter Feed Widget... I've set it up per the instructions in the documentation (all keys/tokens/secrete keys have been saved in the .php, and permissions set to 755 in the "cache" folder) yet I only get the spinning preloader.gif. I've searched this topic here and found another way to check my own work: I've looked at the Network Tab on the Inspector to verify that I get a response in the XHR request. I can see the response, and within the response I recognize text from the tweet I was hoping to display on the widget. Could you help me figure out how to get it to show up properly in the widget?
The website is:

and the feed is located just above the footer. Thanks in advance!

Update:
I've noticed in the tweets.php code that in the absence of a "data-username" property in the twitter element, a default of "twitter" is used. I removed my username to see if the feed from the "twitter" account would show up in my widget and it does. Some other setting -- perhaps in my Twitter account itself -- is preventing my tweet (I only have one, so far) from being shown in the widget. Any thoughts?

Yet another update:
Here's the part where I must admit how dense I am. In writing my previous update, it occurred to me that a twitter scroller might need more than (1) tweet in order to work. I logged in and posted a second tweet on my account and, voila! Works like a charm.
So, to anyone out there who might be as boneheaded as me: the twitter scroller only works on a feed that has more than one item :P
To the SemiColonWeb team: Keep up the good work! Your theme is the first one I've ever purchased so I have nothing to compare it to, but I'm extremely impressed with how well thought-out everything is!
