This guide is for people who may have purchased an account or maybe just forgot how to do it. The method has changed as netmarble has done a lot of renovations to their site. It's a lot easier to do now. You will need your account name, password, and last 7 of the KSSN used for your account.
How to change your email:
Step 1. Log into your NetMarble account from the main page, not from the dbo login (This seems to work best with IE) and click "My Page"
Step 2. Click on the email option
Step 3. Enter your password and the last 7 of the KSSN
Step 4. Down towards the middle of the page there will be the registered email. Type in the email you want and press the blue button to the right. A pop up will appear. Hit ctrl+c to copy it and paste it into a translator. It will either say that the email can be used, or that it is already used. If it can be used, just press the blue button on the bottom of the page. Press OK when the pop up comes up. On the next screen, just press the blue button.
How to change your password and secret question/answer
(assuming you've already logged in and pressed on my page, step 1 from email change section)
Step 1: Press the password/secret question change button
Step 2: Press the password change button
Step 3: Enter the info then press the blue button
Step 4: Go back to step 2 and press the secret question/answer change button
Step 5: Enter your password and last 7 of your KSSN
Step 6: Select your secret question then type in your secret answer. Press the blue button and you're done.
Everything that I have circled are the buttons you need to push. I hope this helps out. If you still need help, just send me a pm.
