Apple recently pushed out an update , of some sort that affected our EMED server. It causes the podcasts to show a circle with a question mark or the podcast does not begin at all.
The temporary fix for this is to use Safari Browser (an Apple product).You can download Safari, FREE, by going to Apple Downloads. Be sure to put in the email address, but click the box if you don't want them to send stuff.
Once you have Safari downloaded, open it and go to this link, EMED to show the podcasts in your classroom.
You can also type "EMED Math " into the search after you open Safari ~ and find the link that way.
Sorry for the inconvenience. Good Luck in your test reviews!
