[helpme] Can't Upload or Download (LOG INCLUDED)

My FTP was working fine few days ago.
but all of sudden I cannot upload or download from any ftp servers.
I have no firewall at all.
I tried few computers on my same office network, but non of them worked.
I figure that it could be my router, but cannot find a way to fix this problem.
please help me.
