I can't upload via FTP anymore...What's wrong?

[PixelSierra]

This morning and yesterday evening I tried several times to upload via FTP but I always get this:

WINSOCK.DLL: WinSock 2.0
WS_FTP Pro, Version 7.6, 2002.08.23 (in black letters)

Finding Host ftp.freepgs.com ...
Connecting to 64.193.110.130:21
Connected to 64.193.110.130:21 in 0.015, Waiting for Server Response (in green letters and then it loads for a while)

And then after a while I always get this:

Connection closed by remote host. (in red letters)

A few weeks ago I uploaded several times via FTP with no problems at all and now I suddenly can't upload anymore...What's wrong and what must I do so that I can upload via FTP again?

I would appreciate it greatly if someone could help me out...
