Hi there! I hate to hear that you're running into this, so let's see if we can get this sorted out.
I hopped into your account and was able to work without interruption in Chrome, Firefox, and Safari. Can you let me know what happens if you visit this direct link to your Audience page: https://app.e2ma.net/app2/audience/? I did just refresh your Emma username settings, so you'll want to clear your cache & cookies on your current browser before logging in again.
