Hi, I'm trying to regain access to another windows account (created this one so I could post). I only created the account so I could use xbox live so being a bit stupid did not record the details I would need to access it. Earlier this year I got onto it (just so I could access mobile phone apps for xbox) and was working fine till my laptop, which I was signed into at the time crashed and failed to load windows, resulting in it needing to be wiped clean. I discovered this issue when I tried accessing my mobile apps but couldn't log in. When I went onto my xbox live I noticed it was signing into messenger which I had recently fixed, I put in the details required but came up telling me their was an issue with the account. So I tried logging into my windows live account and found I couldn't log in, told that It was temporarily blocked. So I tried changing the password, but email sent would only go to the account which was blocked so I tried security question which since it had been a long time I have forgotten what the answer was. So I then tried the questionnaire which is almost impossible to fill if u have never sent emails from it (I have another email account which I use instead for sending emails). So I have tried this a few times and have got the same answer again and again, not enough info to verify account, account blocked temporarily. Since I could still log into xbox live, play games and the rest, with no issues apart from messenger I decided to leave it at that. Now though xbox live has asked for a security update which requires email and password and since my account is blocked it gives error code 8015002E and signs me out. 

I'm out of options, no one is able to give me a straight answer, I have no idea if someone has managed to hack it or not. I cant even transfer my xbox live to another account, I really don't want to lose all the money I have spent on Microsoft points either.

Please if anyone can help me I will be grateful
