I purchased and installed the $4.99 version on my daughters Ipod touch. Then I went on-line and purchased the Premier edition. I was able to list my daughter as a user on Premier, but can't figure out how to register her Ipod. I log in from the Ipod, but that doesn't seem to register the device. Her Ipod is using version 4.3. SO, for example, I put a block on Facebook on-line for my daughter, but it doesn't stop her Ipod from going to the webpage.
