Using Windows Media Player 9.00.00.2980 up to about 6 months ago I could listen to one of the radio stations from the web. A *.wma file, about 7 megs, was saved to my temp internet folder. I could then play this file later, if I chose. Now, I listen just like before, but the file saved is a *.dat, which I cannot open with any media player to listen. I did not see any settings within the player to change this. What can I do without buying any of the software that's on the streaming software link?

Thanks!
