Q.: I can't log in! What should I do?
A.: If you a seeing a message that your e-mail does not exist - then possibly you were trying to log in Zendesk. Please try log in here.
Please also make sure an e-mail address you enter is correct. Maybe you have made a mistake (a typo, for example) while signing up.
If all the data entered is correct, try to reset your passrowd.
If you do not remember your password, you can reset it or use "remind password" option.
