Hi adrianmartinez,

Welcome to the Support Communities!

It appears that you have another email account (Gmail) that you can change to for your primary email?  The article below explains how to change your Apple ID.  If you are not able to resolve the issue, I'm also including a link to our Apple ID Support Team.

Apple ID: Changing your Apple ID

http://support.apple.com/kb/HT5621

Before you change your Apple ID:

• Sign out of all Apple features and services that you use with your current Apple ID.
• Make sure that the email address you want to use for your Apple ID meets these conditions:
  • The email address is one that you use regularly, because it will be the primary email address for your Apple ID.
  • The email address is not associated with any other Apple ID.
  • The email address is not an iCloud email address, which is already an Apple ID. iCloud email addresses end with @icloud.com, @me.com, or @mac.com.
