Well at least we're a little bit further forward! I dont's see this as a file/folders permission, as all you're trying to do is to upload your files and folders into your site's root directory.
When you say you are getting the same error, do you mean that you are getting all the same errors that you listed in your first post in this thread? i.e:
An FTP error occurred - cannot put somefile.php. Access denied. The file may not exist, or there could be a permission problem. Make sure you have proper authorization on the server and the server is properly configured.
I know you have tried different settings for the remote host FTP in Dreamweaver's site definition, but I can't help thinking that that is where the problem is, that there is a combination of settings that you haven't tried yet.
So far the options seem to be:
22.214.171.124 (this is your domain's IP)
/public_html/ ( for Primary Domains on cPanel accounts)
/public_html/somesubdirectory ( for Subdomains and Addon Domains if when connecting with the cPanel)
/ ( for Subdomains and Addon Domains when connecting with a seperate FTP user)
same as your cPanel user name
*HostGator Note: Only cPanel and Plesk usernames will be able to connect using 'user' logins. All other FTP users must use either 'email@example.com' or 'user+domain.com' syntax when attempting to connect via FTP.
same as your cPanel password
Did you ever find that 'second email'?
Can you access your cPanel for your spotgrabber domain? Login to your main (reseller) control panel at: whm and check your ftp details there.
So all I can think of to try at this stage, is to try various combinations of login details for the remote FTP settings in your DW site definition, starting with:
FTP Host: 126.96.36.199
Host directory: /public_html/
Login: same as your cPanel user name
Password: same as your cPanel password
Then try some other combos.
I also sincerely think you should email HostGator, explain your problem, and ask for specific instructions. That would be my first move every time!
Ian's suggestion of trying a seperate FTP program (like the free FileZilla program, or the Trial version of CuteFTP is definitely worth looking at too.
Let us know how you get on,
Cheers and good luck!
