Probably the stupidest question in the world......

well that numbers and dots are the IP address (the remote site)

so in flashfxp press F8, then enter the IP in the "server or URL" field, the the port is more than likely 21, then enter your username and password, now press connect.

if all done right, flashfxp wil now log you into your ftp site where u can do what you need to do
