I'm sorry but without more information there's not much anyone can do for you but here are a few general tips:
What operating system and web browser are you using?
Are you using the latest version of the Flash player 15.0.0.152? Check your version and update if nessesary here: http://www.adobe.com/software/flash/about/
People who have problems with IE frequently have better luck with either FireFox or Chrome, try one of those.
If all else fails, as a work around try going directly to the networks own web site and watch from there.
