NOTION Music Forum

Hi. I have tried to do the update to Notion for iPad 2 several times with no success. I have tried through the Apple App update and online at Notion.com. The update downloads fine from Notion.com website. But it then says "open in Notion". I click on the button but it never opens in Notion. Any ideas about how I can fix this?
Thanks Jeff

Can anybody in administration help me out? I can't use the program at all.
Thanks Jeff
