I'm Jaehwi from Koreanclass101.com
Thank you for letting us the issue.
We've checked the lesson at http://www.koreanclass101.com/2011/04/2 ... structure/
(Lesson 2 Basic Bootcamp) and we couldn't find the problem to listen the audio file.
There could be some issues on cache (the previously downloaded files) or some other issues. To check which is the reason to make the problem on your computer, could you check the lesson with different web browser such as Google chrome or FireFox? If you have no problem of loading the lesson on different web-browsers, please delete cache files and try to load it again. If you'd still have the same problem, please let us know.
We are sorry for the inconvenience.
