First, make sure you have the proper capabilities set. The error you're getting is what you'd see if you didn't declare the right CAP_ID . Here is a screenshot:

Regarding file paths, depending where the file is stored, you may need to use the double-slash. I had a similar issue, I resolved by using the following approach:

"isostore:shared\\folderName\\NameOfFile.mp3"
