Here are some tips to get your Konami ID registered.
Get ready to do some speed typing because anything less will get you the inactivity error. I recommend using Firefox as your browser, as I also tried with Internet Explorer and it didn't work as well.
Go to https://id.konami.net/login.do
The next page asks you to enter your country (which is already at United States), your language (already set at English), and your Date of Birth. Click Next
The following page requires you to agree to the Terms and Conditions, so without reading anything click agree.
This next page is where you need to do your speed typing. I suggest using the tab button to get to each line as fast as possible. The process (only the required info) will look something like this:
Konami ID (must be 8 characters or over using letters, numbers, and underscores. Must be lower case letters)
Password (must be 8 characters or over using letters, numbers)
Mothers Maiden Name
GAME ID (cannot be the same as Konami ID, must be 8 characters or over, must use lower case letters)
