I purchased Systematic Theology (3 Vol.) by Charles Hodge and it loaded it onto my system but will not unlock it. Before that purchase I purchased several other titles which loaded AND unlocked with no problems whatsoever. I forgot to put Hodge's work on the list so I purchased it later.
I've tried again to unlock it through my existing purchase but it will not do so. Any suggestions? I have email Logos.
