Do Your Video Tutorials No Longer Work on the iPad?

I am a big fan of the iPad and took special care to make the video tutorials work on the iPad.  For some reason, our new ad program that displays an advertisement at the beginning of the tutorial, is not showing up on the iPad, and even though it is not displaying,  it needs to be tapped, in order to close and start the tutorial.  We are looking into resolving this issue and may discontinue this ad service if it cannot be fixed.  For now, when using an Ipad to view the tutorials, just tap near the center of the black video player that pops up.  this should close the backed out ad and start running the tutorial.  Either that or you will be whisked off to the advertisers site!   Akkkkkk !
