Connection problems even after checkin

Yesterday I installed Windows SP2.
After I installed it I wanted to visit my ftp with SmartFTP. Normally you get an pop-up if you want to enable internet for the application or not. But this time, it didn't

So I went to my SP2 firewall and checked if SmartFTP was allowed. It was. But I still can't connect to the ftp

This is my report

[20:38:29] SmartFTP v2.0.996.28
[20:38:30] Resolving host name "roxxxxxxx.ro.funpic.de"
[20:38:30] Connecting to 213.xxx.241.xx Port: 21
[20:38:30] Connected to roxxxxxxx.ro.funpic.de.
[20:38:38] De software op uw hostcomputer heeft een verbinding verbroken.
[20:38:38] Cannot login waiting to retry (30s)...


It's in Dutch I know, but it says That software on my pc blocks the connection.

Any ideas?
