DynDNS and DD-WRT - Error validating DYNDNS svr answer

I have DD-WRT v24-sp2 and I had to spend some time trying to get DynDNS configuration working. The DD-WRT wiki for DDNS seems a bit confusing... but here's how to fix the error below:
"W:INADYN: Error validating DYNDNS svr answer. Check usr,pass,hostname! (HTTP/1.1 200 OK" 

Complete your DDNS configuration with the following information:

DDNS Service: Custom
Do not use external IP check: No
DYNDNS Server: members.dyndns.org (you do need the members subdomain)
User Name: [ your user name - usually not email ]
Password: [ your password ]
Host Name: [ your hostname as it shows on your account - usually hostname.dyndns.org ]
URL: /nic/update?
Additional DDNS Options: --dyndns_system dyndns@dyndns.org --ip_server_name checkip.dyndns.org:8245 /

Click on "Save" and then on "Apply Settings". You should see a sucessfull update at the status:

Sat Jul 27 16:59:37 2013: INADYN: Started 'INADYN Advanced version 1.96-ADV' - dynamic DNS updater. 
Sat Jul 27 16:59:37 2013: I:INADYN: IP address for alias 'fakehost.dyndns.org' needs update to '1.1.1.1' 
Sat Jul 27 16:59:37 2013: I:INADYN: Alias 'fakehost.dyndns.org' to IP '1.1.1.1' updated successfully.

Awesome, just saved me a ton of hassle. Do you think when you have a moment, you could explain what each line does in detail? don't want to be a newb forever, but not smart enough to move ahead without help, I'm afraid...

Guess this trick quit working? I'm using an old firmware (SVN revision 14896. For some reason the URL and Additional Options boxes highlight with this info and won't update. Any help appreciated!
