Hi! Thank you for offering this product!
I'm running WP version 3.4.2, and was able to install this plugin automatically from the admin panel. But there are a couple of problems.
I've tried to update my twitter account with this plugin, and while it looks like it's going through, my twitter feed remains unchanged. I've tried logging off and logging back in through the plugin to authenticate the app twice now.
It's also able to detect I have 4 statuses on the new twitter account, but just below that, suggests there are "no statuses", and won't display the ones already posted.
Here's a screenshot of how the plugin looks on the dashboard once installed: http://www.webpagescreenshot.info/i/24247-11292012102502pm.png
