I would use the same log in information with the web site (www.playstation.com). Go to my account, then to - manage your Sony Entertainment Network (SEN) account. Check to see if the ps vita is an activated device on that account.
If its not...your vita is associated with another SEN account. Activate the Vita on that account and you should be good.
