A few us ran some tests on a random selection of seminars from each year and they all played the full file.
A few things to note:
1. The audio files are fairly large. If you skip ahead, it can take a few seconds or so for the buffer to catch up. Try waiting a little bit when you hit the dead spot and see if it loads.
2. If you're trying to access on mobile, it could very well be a bandwidth issue
3. If you're still experiencing this issue you can right click the audio icon and click the "Save link as" option and it will allow you to save the audio file and then you can load it onto your computer or mobile device which should cut down on any buffer/bandwidth issues.
If you're still having issues, please email me and we can work on diagnosing the issue further.
And if anyone else out there on the Forum is having issues, feel free to email me as well.
Cheers,
