Party Planner

I really enjoyed using this app to plan my daughters Sweet 16 last year. Last year, I used it to plan my 50th. I wish that I was also able to use to send e-vites; especially if I could use my own pics for themes. This would be great because all of the info needed is already in the app. That is true "one stop shopping".
This year, Im trying to plan a family reunion & the app will not open on my iPad. It works on my iPhone 5s but not my tablet. I have renew my subscription & it still doesnt work. It really helps to have everything together & be be able to collaborate with others. But if I cant get it open, what good is it.
