I have not login to Adwords for about a year after several times paid hundred of $ to them but now it looks like my account is dissapeared because could not login or has yahoo email not allowed for user id anymore ? Anyone has the same experience account deleted without notice ? Seems Google has too much money till could delete account arbitrarily.
i don't think so that Google deleted account for not logging in that too without notice. you said that you are using Yahoo! ID for logging in, have you used this ID to login to your Yahoo! account?
The fact is that cause from the saved report the login id is yahoo email. Maybe also that now Google Adwords requires/impose using its own Gmail for login but why should deleting past non gmail login account.
