new user FTP problem

new server got it yesterday ( for learning ,tests,remote backups )
Cpanel/WHM latest release&centos3.4

i can login ftp as a root but when i try to login from newly created user account i get this message :

Command: USER username
Response: 331 Password required for username.
Command: PASS ********
Response: 230 User username logged in.
Status: Connected
Status: Retrieving directory listing...
Command: CWD /username/
Response: 550 /username/: No such file or directory
Error: Could not retrieve directory listing

am using FileZilla 2.2.3 ftp

from user acount cPanel i can upload files from file manager and i can browse the site from this url: http://xx.xxx.xxx.xx/~username/

there is no domain name used for the newly created account

host company providing free hardware firewall ( dont know if this is related to ftp problem )

from where i should start to fix this problem ?
