xKurusux

I was deleting a alternate account. Then when I went to the market place I was still signed in as that deleted account. And it said that name still so when I went to delete it again, it instead deleted the main one I have. I really don't want to lose my accoutn so I want to know how so save it from expiring or somehow reactivate it. Account name is xKurusux. If anyone from linden can help me with this I'll be very greatful.
