Can’t logon My SQL Administrator

I am so lost. I am simply trying to logon to My SQL Administrator so that I can create a backup to upload onto a new server.

I can’t even logon. I get all types of errors and I feel I’ve typed in everything I can think of.

The logon screen wants:

Stored Connection:
Server Host: Port:
User Name:
Password:

No matter what I do, I get an error and get nowhere.

Please, what am I doing wrong?

Somehow I managed to get WP installed on the server and was even able to install the themes I like but here I am stuck.

Thank you so much for any assistance on this. I’ve been at it for hours.
