From the Introduction thread -
You need to login on the server(i believe you can get user-name and password from your admin who make server for ODK) then you can download data from that server if your server is web-based.
Or you can do one more thing you can pull data from device on which you did survey and then pull. For this you can go through with below link that can help you.
Thanks so much, Neredra, I will try both options and give you a feedback tomorrow just closed from work.
