Error when deactivating and activating a user in the email integration

Hi there,

I have purchased the Email Notifications Integration and managed to successfully activate the extra emails for all team members. But then I deactivated myself and I can't reactivate my account. I removed myself by clicking on the green switch in the right side of my name. I tried to reactivate my account by clicking on the same switch, which is grey now, because it's not active. It turned to green and I got the message "An error occurred. Please contact support". While it turned green, the other switches are still grey so I can't activate them. I would appreciate some help with this, thank you. The account is registered on the same email address as this one.
