I have lost my money

Mac Os 10.10.5 I have THINGS on iPad, so I thought it would be good to have it on my Mac Pro, it works the first time you launch it, then crashes EVERY launch afterword. I have owned and worked with Mac for 15 years and know my way around, never have I bought an app that failed on this level, SAVE your money, trust this review, I am not bitter, Just concerned that others may have the same horrible, unsatisfactory experience.
