View and Pay Invoice

I am working a second company that the CC option under Preferences>Payments>Company Preferences>Online Payments> Credit Card, it will not allow me to check the box and when I try it says I already have the service, log off to update QB and I did and the box is still not checked and we still can’t take payment.  the Primary company currently accepts payments through QB but I can’t get the second company going, what am I missing?
