I'm able to log into the website, but not the game

[Groovinchip]

Hi there, I'm new to this game. I created an account and downloaded the game on macOS last week. I have been able to log into the website without issue in all that time, but I've never been able to log into the game - I get "Invalid username or password" errors every time. I've tried both login options (silver login and gold login) with no success. I even tried changing my password today, and that did not help either. I would appreciate some support for this issue.

 

Thanks!
