Are you saying that our licenses we have been using from previous versions (versions 3-5 in my case) of PDFArchitect do not work for the current version(6)? I need to repurchase version 6 on a yearly basis from now on and I cannot use my previous professional version? If this is the case, I feel ripped off. Changing the licensing model with no way to continue with no loyalty upgrade looks like you have abandoned clients that got you here. Is this the case? Have you chosen to invalidate previous client's licenses for the current version and versions going forward? Have you chosen to embrace Adobe's licensing model?
