I purchased DropCopy Pro in 2014 in the Appstore. due to a hard disk error i had to install the macOs new.
So i clicked on the install button in the App Store and downloaded the app again but i can't open it.
While starting the app for the first time the apple ID and Password window poos up and tells me to enter the apple id and the password where the app was purchased with. Due to the fact that I have only one ID it s easy i thought but the app doesn't start.
A second click on the app icon in Launch app brings nothing.
