You bought your vbgallery from another company or when we first aquired it for the $59.00 price correct! You have access to vbgallery should you wish to use it. That is what you paid for.
What you do not have access to is Photopost Pro. Only those users whom purchased Photopost Pro licenses since the license merge in September of 2007 I beleive would have access to install or use either license. That is how it works because those users paid the normal full price of $129.00 or maybe $99.00 which sometimes is the sale price.
