fwiw - when I release a new version, never extract it over your old version either. Always to a new folder of its own. That will also cause issues. And any AVN where you're using mods, you should always check the version of the mod before you apply it. Those mods change a lot of script files and can overwrite the newer one with an older one. Good luck :)
I picked up a fresh download, purged the old installation as well as the save folder for it then installed the fresh download in a new folder. I just started the game fresh at day one and have worked through Pet Bond 1 (Alexi). At point of introduction to Coach Vivian. So. Still have some ground to cover so I can find out if the images that where missing before are now accessible. Fingers crossed and as with Serenity C2. Looking forward to next update releases! Love your works N2!! Cannot wait to see what else you come up with in the future!
