Did what you said and now it does not like my login or password, i have checked the email with these details all seem to be the same, have you got any more bright ideas?
did you ask your host/provider whether your password and your username are correct?
You could try connecting to your FTP not with DW features, but with a different software. I am using filezilla with great success and it looks for me easier in daily struggle, here is the link to get it and to get to know it:
And here I'll quote a Nancy hint:
Try toggling Passive and/or Secure FTP on/off.
Your web host might have changed upload requirements to improve security.
Another thing to check is your Anti-virus and Firewall settings. If they are too restrictive, DW may not have permission to connect to the remote server.
One of the hosts I use has introduced a new security feature where they require users to log in online and lock/unlock FTP access, They reccommend that you lock a site when not using it and provide an option to unlock to a time period or to a specific IP address. No matter what I do, Dreamweaver seems to not recognise my login details every time I start up. I have to log-in online, lock and unlock FTP and then DW has no trouble with a sync. It's irritating.
