How to change live accounts

Hi, I downloaded eM client today to move from Thunderbird. I use two email accounts. One gmail and a btmail account. During the set up eM had set up two gmails and two bt mail accounts and says only two can be live at any one time. It has chosed two bt mails. I would like to change one of the BT mails for a gmail. How do I do this? thanks

Seems you have duplicated your account setup. Go to Menu > Tools > Accounts and delete the duplicates so you only have one Gmail and one BT account.
