I can't log on to ftp.drivehq.com. It asks me for login/password, but doesn't accept it. I can't connect at all to proftp.drivehq.com (from a different IP than the one my camera is on).
I have no idea what is considered normal usage. I've used other FTP services with no problems.
If my IP is temporarily blocked, then unblock it. Right now I'm paying for something I can't use.
