I created a dB in Zymic's database management page.
I tried to go into PHPmyadmin, but it was terribly slow and never did let me edit my dB.
So, maybe NaviCat or FileZilla can be helpful? But I can't establish a connection. What gives?
Host: mywebsite.zxq.net
Username: 12345_myuserid
Password: ******** (this is the MySQL/PHPmyadmin pw)
Port: 21

Response: 530 Login authentication failed

Am I missing something? I want a quick way to work with my dB. How?

filezilla is an ftp client, not a database management tool. Remote connections aren't allowed, so you can't use a third party app to manage your zymic databases atm.
