SwitchAdmin on "[Plugin: oAuth Twitter Feed for Developers] Search Feed"

I am trying to integrate your changes into the current plugin and I am not getting any results (nor errors). I have been using the example layout code as a starting point (https://github.com/stormuk/storm-twitter-for-wordpress/wiki/Example-code-to-layout-tweets) and I have tried changing the initial call from:

$tweets = getTweets(4, 'twitteruser', array('include_rts'=>true));
foreach($tweets as $tweet){
if($tweet['text']){
echo '<li class="tweet">';
...etc.

to:

$tweets = searchTweets(4, array('q'=>'%23Cambridge'));
foreach($tweets as $tweet){
if($tweet['text']){
echo '<li class="tweet">';
...etc.

But no results are being displayed. Is there something that I am doing wrong or missing? I have implemented the changes to both twitter-feed-for-developers.php and StormTwitter.class.php and as I said I am not seeing any errors.

Thanks!
