DreamboxEdit is not conecting to Vu+ Solo. Why?

Hello to all members of the forum. I need some help. I just bought a Vu+ Solo on which i installed Blackhole 2.0.5, Tspanel 7.2, and cccam 2.3 (using tspanel menu). Then I connected to Vu+ Solo using Dreambox control center and copy cccam.cfg file to receiver using ftp with user "root" and password "dreambox" and it was ok. Then i tried to connect to VU+ solo using DreamboxEdit using same user/password, same IP adress, port 21 for FTP (80 HTTP) and when I push the "Test IP conection" button it says "Sucesfuly conected to the Dreambox on IP adress ...." but when I push the "Test username password" button it says "Could not conect to the Dreambox on addres 192.168.0.6 port 21. Check the IP address and the port number and try again". I try seting fpt to passive and active and same error message. What am I doing wrong??? The IP addres is correct because i checked on the receiver in the network menu. Is the receiver using a different port for FTP then 21??? What user/password must I type (root/dreambox is ok?)? Any ideeas??? Thank you.
