Wage expense linked account is not defined

SUGGESTED

I use Sage accounting with no employees my year end is march 31`.  Everything balances fine but when I went to start the new year I get the message "this module cannot leave history mode because the 'Wage Expense' linked account is not defined.
can't find a an account  called Wage Expense and this is getting very frustrating.  
Can anyone help and provide simple instructions for sorting this out.   Please.....and thank you.
