Doesnt open

Worked fine. After the most recent update, it wont even open. Whats the point?

Before it stopped crashing, it was OK. Features are kind of basic. There isnt a lot of room for customization. We basically have 2 guest lists (one small group for a private ceremony and one large group for our reception) and Im not able to customize it the way I was hoping to. I like being able to view my guest list and make changes on the go, but really, its a glorified spreadsheet. A Google doc would work just as well.
