Use my billing adreess check box is gone...

Hi Lads…



I think I have misconfigured something while setting up my shop… well the story is after setting up all localizations, languages, reward points, shippments, etc… I went to make an “order test” and I realized the USE MY BILLING ADREESS WAS GONE, I have been checking every section in the admin backend and I didnt find anything about it…I´m just getting crazy.



Does someone know where the **** is this option located to switch it on?



Thanks

Any sugg??
