I want to hear audio from a particular website. The site offers windows media player as a way to listen. I click on this and I was told that I don't have windows media player and I need to download it to listen...click here. So I clicked and downloaded windows media player for mac osx. Then I click the new icon for windows media and I get the following message: "There is no default application specified to open the document "Windows Media. sitx"...Choose application" This is not the first time I have received this kind of message. In fact I have not yet been successful in opening ANYTHING I have downloaded because I don't know how to get passed this "Choose application" part. This has got to be basic Mac knowledge because NOWHERE in the manuals can I find instructions about on how to proceed. Yes I'm new to Mac. Will someone please give me some advice on how to or where to look to learn???
