You can open your new download anywhere. The binary writes copies of your save to %appadata%/ChasingSunsets/ so it should be aware of any previous saves no matter where you stored the last update. (As long as it's under the same username on the same PC)
LOL! Indeed that was the issue. I’d originally engaged on my MAC Air, but then attempted 6 on my desktop. All good now. Enjoying your writing and art thoroughly. There are 9 quality AVNs (in my humble opinion) worthy of following, which are of professional caliber, and yours is in the top 3. Keep up that quality production!
