Signal has been Used

 
My signal had been use by previous trader. The previous trader has deleted from his account. Now i wish to put it back to become my own signal. but system shown that my signal had been use can not be signal again. I m very sure the previous trader has deleted from this account. Kindly advice.  
 
Start an new signal.
 
You cannot use previous account to provide new signal. You have to create new account in order to do.
