I have tried log off/Login, different browsers and even the possibility of going over the MB upload limit. Can't find anything. I have sent the details.

My guess would be Twitter isn't allowing it because your site is not SSL enabled, I don't believe Twitter, like Facebook, allows embedded players that are not coming from an SSL enabled site.
