MJH038: There have been lots of intermittent problems reported with PD9 and PD10 (don't know about before that) and .mp3 files. Personally, I convert all of my files to .wav format, which seems to solve the problem for everyone. I know that doesn't solve the issue of why PD10 occasionally chokes on .mp3 files, but that is the way it is now, as far as I know. So, I just go with the flow. I don't enjoy wasting my time making coasters.
There are free programs out there to convert .mp3 files to .wav format.
Hope this helps. Have a great day.
Regards,
