Pyro Play Error

Help, I am no computer wizard but my new Pyro 5 program is giving me fits. It'll record my LPs, which is what I got it for, but won't PLAY anything. Instead, I get an error message saying: "Pyro could not play this file. Please make sure the file is not in use." My Windows Media Player will play the new files made from my LPs. I close everything but Pyro, but no deal.

I'm sure the errow is mine, just don't know what it is.

Thanks for any help.
