I bought an xbox over the internet and it came with parental control enabled and I do not know ...

You'll need to contact support and they can help you reset it. 1-800-4my-xbox if you're in the US/Canada or http://support.xbox.com/contact-us

Hi, you can enable parental controls in your or yours son´s account. With it enable you can disable purchases over xbox.com or you console.

Just folow these steps :

I had it happen too. At least all the upgrades I had won saved but had to start the game over from scratch. I'd play contracts but it won't let me do it. Says I am blocked due to parental controls. I have never enabled parental controls.

I'm not positive this will work but The only thing that I can think of is that you'd need to reset you're xbox. You'll need a flash drive formatted to your console so you can move anything an everything you want to keep onto it. This is because when you
reset it you will erase everything that was ever put onto the xbox and go back to factory defaults. Read thtough all instructions before starting.

1.) plug in the flash drive and format it to your xbox

2.)go to settings

3.) Press a on system

4.) Press a on storage

5.) press "Y" on your hard drive or storage device you have your stuff on

6.) Press transfer content

7.) Move it to your flash drive or backup device

8.) Once its done moving everything exit out and remove the flash drive

9.) press "Y" on your storage device again (Hard drive)

10.) Press "A" on format and then yes.

REMEMBER TO MAKE SURE YOU BACKED UP EVERYTHING YOU WANT TO KEEP ON A SEPARATE STORAGE DEVICE. And to be safe don't have it plugged into your xbox. Remember I'm not positive this will work but It's the only thing I can think of. If you would rather watch
