Help a newbie with FTP!

[seknd]

I've been searching for answer for this few days now, after i finally managed to install ispCP-Omega 1.0.7, and i've got my control panel working to cp.mydomain.org and now im stuck with filemanager/ftp. In control panel it says my ftp works on my IP and when i try to connect with my user which i made in cp and with root user it says "

Unable to login to FTP server localhost with username ___*

Are you sure your username and password are correct? Please contact your ISP helpdesk or system administrator for help."

I dont know should it be localhost there.. my username is right, my password is right.. I've pointed(dont know is it the right word for this) DNS http://ftp.mydomain.org so i could connect with that address in filezilla or someother prog like that but its not working.

Ask me if you need more info/logs etc. And sorry for my english(been awake over 24h struggling with this.)

OS: Ubuntu 12.10 LTS
