I'm getting this error when I try to connect.

Failed: FTP response 421 received: Server closed connection

What could be wrong? I have upgraded to a paid account. I'm using an affiliate network and using their interface to place data in the folder. I can log in using an ftp client from my home computer. No problems there.

Please help. Thanks.

Please send more detailed error info (FTP log) to DriveHQ customer support. It seems to be not our problem as you can connect via regular FTP client.
