Resolved the issue mentioned earlier in the "informational" post about the update (i.e. possible conflict with Contact Form 7), and chose to upgrade to the Pro version so as to retain the "filmstrip" style gallery unavailable in the free version of the plugin. We'd previously leveraged the NextGen Scroll Gallery extension to meet our display requirements. It is no longer supported and creates deep script conflict with both the gallery as well as the site's theme (modified wp-creativix with no child).
On download and install of Pro, there is no way to interact with the plugin. Meaning that there are no administrative options/settings installed with Pro. The only way I can get the administrative options is to install the free version alongside Pro, though the options that come part and parcel with Pro aren't at all available and my only options are "basic".
I would very much like to continue my patronage, but this is unfortunately going to be a make or break for us.
