hello heyyo
there is a 'send me my password' link
*click here*
but bear in mind the password for http & email access, may not work for ftp, if you have ever changed it, since registering.
ftp often 'sticks' with the original username/password combo you were first given by ntl, so if, even after using the above link, it still doesn't work, you can try the original password, or, you may have to contact technical support, to get it sorted.
