iPad to computer

I did all my ordering both (Happy Harping and the Blues DVD’s) on my iPad. My desktop has my midi synth and all my composting stuff but I can’t get anything but the adds for lessons on it. All the extras only show up on my iPad but the o’s on the iPad doesn’t show any buttons to push. Is there a workaround for this or are the extras only available on the device you ordered from. I am most probably overlooking something obvious, I intend to overthink things.

Thanx Rob

No Flash support on iPad is the prob I Just wondered how I could change login to my computer so I could use all the extras

Thanx. Rob
