How do I go about setting up FTP?

Hi there, I am trying to install and activate some themes and plugins through my premium memberships. I've tried to download the plugins/themes and install through the plugin page...doesn't work. I've also tried to do it manually. That's where I am stuck. Apparently I need to reconfigure my ftp. I use filezilla. It appears that I no longer can connect to the server...of course I can't (lol), I switched from fatcow to psek. It was much easier setting up the ftp account through fatcow. The instructions for psek are not clear :slight_frown:

Can someone help?
