From here it looks like a "bad" character has crept into the file you are processing.
Here's a few things to try:
1. See if the eg files which come with mma work. If they do, then continue to 2. If not, we have a problem. Let me know.
2. Try re-typing the "groove folk" line. Try a different editor. I'm assuming you are using notepad, which should be fine. But, it is quite possible for a "bad" character to get entered by mistake. THe error message you are getting is telling you that a "0x0c" character is in the file. Most likely, you have a "Form Feed" character instead of a "Space". And you'll beat yourself up figuring it out since they both appear as SPACE in your editor.
If all this still doesn't work send me the bad file as an attachment to
bob@mellowood.ca.
Please let us know!
