Connection and Filesize Problem

[junky]

Hi All
I like FlashFXP, I'm using 3.0.2 and have a connectionproblem to the site where I've registered here http://free.prohosting.com/

it says Data socket error.. I've searched in Prohostig tutorirals and found this
============================
Data socket error
This error means that your FTP client is set to "Active Transfer Mode" and you will need to set it to "Passive Transfer Mode". Please use the help section of your FTP client or contact the developer of your FTP client to find out how to set your FTP client to "Passive Transfer Mode"
============================
In Options ==>Preferences ==>Connetion "Use Passive Mode" is on
Where is the Problem? how can I log in into my site?
