Thread:Project:Support desk/Mediaplayer stopped working

Hi I am using: Mediawiki 1.15.4 PHP/5.3.0 MySQL5.1.36

I would be grateful for any help with this problem. For some reason that I cannot work out my mediaplayer has stopped working. I don't know exactly when it stopped as I only recently revisited the a page where the player was/should have been working. There is a large space where the player should be and the player appears to be attempting to communicate because the little thing at the top of the page keeps spinning as though it is in the process of downloading.

Thank you
