Not working!

I’ve been so happy with Dashlane for several years, but today I woke to a message telling me the Dashlane App is “damaged” and to reinstall. Going through the process it looks like I have to purchase it again? I’m not sure what’s up but nothing’s working. There’s a ghost in the machine….please repair so I can get back to business again. I have a Mac, by the way. I totally rely on Dashlane for my passwords so PLEASE fix ASAP? Thank you very much.
