How Could This Have Happened?

Hi there,

I am hoping that someone with some technical knowledge can let me know how my Warrior Profile was completely hijacked.

I signed in yesterday (I am hoping to be sponsored to the War Room) and found that my profile had been completely hacked - the only thing left standing of mine was my avatar. I wrote to support who nicely changed my password for me in the hopes of stopping this, but this morning when I went in to change my details back to "me" I found that who ever had been in my profile had changed

My tag line - to Professional SEO (I don't even know SEO)
My twitter name - to seo-tips-triks - I am wisecrone333
My Url - to www.deepakgautam.com - I use www.youempowerlife.com
My location - to somewhere in USA - I live in NZ
My age - to march in 1985 - I wish, I was born in 1961
My occupation - to building websites - like I could do that professionally

And my signature line to include videos from Yahoo among other things.

I was really upset about it because I pride myself on being honest in my dealings with warriors and these changes were totally misrepresenting who I am and what I do - can someone give me some advice on how this could have happened (I am the only person who has access to my computer) and what I can do to stop it happening again?

Any help would be appreciated - thanks
