In version 1.9 is not working
@TheElectroclassic: Twitter.com switched off the API we are using for reading twitter feeds for their website into BoinxTV. We are already working on a bug fix!
@TheElectroclassic Yesterday we released BoinxTV 1.9.1 which has fixed the Twitter issue: You have to login into the Twitter account via the BoinxTV preferences. We are waiting for the AppleReview Team to approve the app for the Mac App Store but you can download it already from our website here: http://boinx.com/download/#boinxtv (please contact support(at)boinx.com if you need a download-license)
