Lost my only admin user. How to create a new one?

Hi I have install the latest akaunting & everything was awesome. By default i have 1 admin ID (says it is called admin and it is using my favorite email-A). I wanted to reserve email-A for my 2nd ID (says it is called manager).  

As a result, i change the email of admin from email-A to email-B via the profile screen. Follow from there, i created manager id with email-A. Everything aspect of manager id works fine. 

However, my admin id seems now becomes limited access with no access to user/roles/permission. Is there anyway i can fix this? unfortunately i am doing it on a live system, so re-installation is not an option. :(

Same problem here.
