Stagevu.com problems

Hi,

I am using a macbook pro and I am unable to download or watch movies from Stagevu.com.... This is the trouble shoot message i am getting :

"Can't watch this? Download the DivX Plus Web Player for Windows or for Mac! Not working? Troubleshoot!
Warning: You currently do not have the DivX Plus Web Player installed."

I have DivX player and the DivX Plus Web Player installed and still unable to watch or download anything from Stagevu.com. On the other hand, those using windows can both download and watch movies.... Please help
