I have tried to enter my new email account and it will not let me first time for this ?
What happens when you try to do that ?
Can you elaborate on that, and maybe do a screenshot of where you get up to and what errors you get when trying to add your account.
Note: Blank out anything personal.
How many email accounts do you already have in em client? Are you using the free version (not still in evaluation, full mode) or a paid version? Free I think is limited to 2 email accounts. Paid, not limited to 2
