Currency display not working

Hi,
My client has received complaints that the currency is not displaying correctly in the last few days.
I have updated to the latest version of curcy.
I have the Auto Select Currency set, I have tried changing the external source to Maxmind, I have the licence key in.
We only show prices to logged in users, it should show Euro to countries I have added to that option, everyone else gets dollar.
When I log in from Ireland it shows dollar, and same is happening for other users.
Can you help?
Regards
Breda
