Upgraded to DW CC 2014.1, FTP/SFTP isn't working at all

Question

There's a HostNexus webserver I usually connect to but since I upgraded to DW CC 2014, it only spits back errors. I can connect successfully to the server in FileZilla (using FTP explicit). I've looked through the forum and tried various suggestions but none have worked:
tried all the FTP modes
--> FTP Explicit: The remote host actively refused the attempt to connect to it. This may be due to 1. destination server name or IP address, 2. port number, 3. server inaccessible, 4. incorrect protocol or settings.
--> FTP Explicit with passive: The remote host actively refused the attempt to connect to it. This may be due to 1. destination server name or IP address, 2. port number, 3. server inaccessible, 4. incorrect protocol or settings.
--> FTP: An unknown error occurred.
--> FTP with passive: An unknown error occurred.
--> FTP Implicit: User limit reached or not authorized to make the connection due to local firewall blocking FTP data.
--> FTP Implicit with passive: User limit reached or not authorized to make the connection due to local firewall blocking FTP data.
reset preferences
specified root folder
contacted HostNexus, they said to change settings to SFTP, port 4000
--> User limit reached or not authorized to make the connection due to local firewall blocking FTP data.
shut down my antivirus/firewall
--> Same error: User limit reached or not authorized to make the connection due to local firewall blocking FTP data.
made sure not connected through any other program
uninstalled CS4
Nothing works.
I really want the efficiency of being able to do everything with DW. What else can I try?
