Are you planning on using your old PhotoPost license separately or are you looking to just use vBgallery with the new setup on the same domain you had been using PhotoPost Pro?
If you had PhotoPost, but are planning on starting over and want to use vBGallery; you can remove the old PhotoPost and install vBGallery instead. You cannot run both - if you want to run a second product, you would purchase a second license.
Please do not PM me for support or sales questions. Thank you for your understanding.
