SmartFTP dont show folders

SmartFTP dont show folders when i'm trying to connect to my own FTPserver... But when i'm using FlashFXP it works! And when i connect to a friends FTPserver it works with SmartFTP and FlashFXP...

I'm behind a router but i have forwarded the ports 20-21 and 50000-50100. And in my firewall i have added my own local/internal ip and my external ip.

SmartFTP says that i'm logged in and i can see the welcome script and after a while it says that connection failed cuase the server didnt respond.

I'm using SSL Explicit cause i have SSL turned on in my Gene6 FTPserver, but still nothing, and i've tried with pasv and active.

Thankful for help
