Can you change the e-mail attached to your parental controls without...

I set it back in october to my Moms email address but then in about february something happened to the address. I don't know what (might have been hacked, might have fallen out of the internet) but it's no longerrecognized. It's no big deal because all the setting were 'allow' but it's one of those things that you know is going to come up eventually and it bugs me. So I was wondering, is there any way to change the email address attached to my parental controls without being able to log into the old one.

I've been told to go to pass.net but thats no use and Idefinitelydon't want to start a new live account. Any ideas?

That's a possibility I guess, it was a hotmail address.

So what happens if your parental controls are set with that address?

Also is there any reason to use you parental controls email if you've made them all 'allow' (e.g. you don't need it to buy subscription or anything right?)
