I have a google account, so I went to adwords and clicked the button that says "click to begin" and I'm pretty sure I filled out all the info, now when I try to log in It says this: You're signed in to Google Accounts under the email and your Google Account password, but this is not a valid AdWords login. If you're an AdWords advertiser, try signing in using your AdWords email and password. Maybe I didn't complete the signing up because it didntn ask me any personal/payment info. Please help.
have u created your AdWords account from same id. in AdWords it's not necessary that you use same email id and password as gmail. if you are not sign up with AdWords yet than first sign up with AdWords than you can access your AdWords account.
