Suddenly not opening on my macbook

I have had this for a few years on my iPhone and it’s great. When I bought my macbook I downloaded the app; however, the app on my phone and mac aren’t connected and if I update a password on my phone it doesn’t update on my mac. Now, I can’t open Keeper at all on my Mac but it’s working fine on my phone. Of course, the password saved on my Mac is the one to pay my bills. Very annoyed.
