Cannot Download - Authentication Required

I am trying to download the OT Social Share extension but am having real difficulties. I have registered with the site but when I try to download I am asked for authentication again. I enter my username and password but these seem not to be recognised and I am repeatedly asked to resubmit.
Any ideas?

Hello,

I've just tried download with your account via firefox and it works perfect. Please clear your browser cache and try again.
