My main avatar,s account seems to have been taken over by my Alt, what do i do about it, accounts cant help, says its a tecnical problem, how the hell do u get tecnical support, cant find a way. Computer associates have been though my computer, no problems with it, so it is a Linden sl problem, how do u contact them to fix it, My main has been logged out of V2 for months, using Phoenix.
