I have owned CS InDesign for years an use it on my iMac and laptop. Recently when I open InDesign CS6 on my laptop it tells me my trial period is over and I need to subscribe or license the product. But I already have a licensed product. Cant find help or a human to talk to on Adobes site. Any suggestions?
