what address are you using in the ftp settings?
Edit:to use that address, you need to configure that domain at co.cc (I'm not sure that you need it if you are using x10hostings name servers though).
the use of ftp.allissonlozz.co.cc relates to the public_ftp folder.
To access your account files, use this:
address: allissonlozz.co.cc
user name and password: same as for cPanel
port: 21
