Huge Thanks go to Patrick who has figured it out!!
Here is a portion of his reply to my PM:
Your are using the /public_html/pnthemes/ as the remote directory, which won't work because that FTP account is restricted to pnthemes as its root, so when you try using that remote directory, it is actually looking for /public_html/pnthemes/public_html/pnthemes/
Just use nothing for the remote directory and that should work for you. I was able to login with the

and not the + sign.
So, here is my correct information:
Access: FTP
FTP Host: weblives.net
Host Directory: [LEAVE BLANK]
Login:
subdomain
weblives.net
Password: pass entered here
