It looks like you are running an old version of Jaksta Music Miner. Can you try downloading and installing the latest version from here:
If this still does not work on either machine, can you check a couple of things:
1. Try different browsers: Safari, Firefox, Chrome. Does this make any difference?
2. Can you say what sites you are recording from? Can you try YouTube (it will capture the audio part) - does this work?
If it still does not work, can you send us the log file again immediately after trying YouTube?
