Can’t open app, crashes – Grid Diary Classic Review

I paid for the pro version years ago. I liked the simplicity of Grid Diary Classic and was not interested in the new Grid Diary 2, not to mention the subscription plan. I was hoping to continue to use the Classic version. Now I can’t even open the app. Seems like the developers don’t care about this version or the people who paid for it.
