Until a week ago, my free account worked great. I am using the FileZilla client.   I was able to upload and dowload files on a regular basis.  I am still able to upload new files.  But now, when I try to download a file, I get the following message:
Response: 530 user (xxxxxxxx) not logged on. Free users can have 2 connections only. Please upgrade to premium service on www.drivehq.com. Price starts at $2.99/month.
I don't understand as I only have one active connection.  Can you please help me understand this error?
