Hi Mixture and thanks for your reply,
I've checked the technical requirements and the only thing it mentions is to download the latest Flash version which I've done. I've even tried an older version as well without result. I tried running IE with administrator rights and that didn't change anything either. I've also tried disabling all security features. I'm thinkining just like yourself that it should work the same on a Mac in Windows as on a PC. Everything is the same but on the Mac for some reason I just cannot get the sound or the animations. On my old PC (or any other PC I've tried for that matter) it just works. I've never had to install or change anything. It has just worked.
