Hi Virgil, I had the same problems as you this morning. I'm also on Mac
(Catalina). I managed to get out of this bad situation by deleting the
application from my Mac, and then downloading the application again and reinstalling it. Now it works. I hope this can help you...

Royaltattoo perfect explanation of how to fix it. Indeed it is often best to uninstall Plarium Play and do a "clean" installation of the new version.

If in your case this also solves your problem let us know, if the problem persists you should contact support. 

Royaltattoo perfecta la esplicacion de como solucionarlo. En efecto muchas veces lo mejor es desinstalar Plarium Play y hacer una instalacion "limpia" de la nueva version.

Si en tu caso esto tambien soluciona tu problema dinoslo, en caso de seguir el problema hay que contactar con soporte. 

Hi RoYalTaTToo,  I tried your solution.  Deleted on my Mac this morning and reinstalled.  Sadly still opens the 'Update Screen automatically then locks at the end.   My Mac is up to date I run Monterey.  Reckon as Elias has suggested my only option is to contact support although as I am not now able to access the game (with a ton of defence out in my city) I may be reaching the point of no return with Sparta.

Did you download from plarium.com the latest version of Plarium Play ?

If you did, it's time to contact support.

Te descargaste desde plarium.com la ultima version de Plarium Play ?

Si lo hiciste si es hora de ponerse en contacto con soporte

Elias,  Yes I did download from Plarium Play and I have contacted support.........awaiting reply but likely to be some time given time differences

But it's already underway 😇, let's wait for the favourable results and let us know about it.
