What is the password for part one? I tried to download the whole file from your Wordpress site first, but got a Access denied message. I then came here to try to download both parts, but it wants a password to be able to extract part one.

For the .world file via Google share - are you signed in to your Google account? It has been set to allow anonymous downloads by "viewers".

For the multipart version, there's no password set. If you get that message means you missed a step. Most likely about renaming the parts of the filename to remove the bits mentioned in the main text.

I am signed into my Google Account on Chrome. Every time I try to click on it, I get the same "Access denied you need to request access or switch to an account that has access." I only have one Google Account and the one I am signed into gives me that message every time I click on the link to download the whole .world file.

How about this one? https://drive.google.com/drive/u/0/...QWtippHh5puOhfg

Are you able to see the contents of the whole shared "Worlds" folder? And does clicking the "Sunlit Tides.world" or right-click -> Download on the file starts the Download?

Is Chrome current or need an update? Or, failing all that, try another browser?
I tried with Firefox and Edge with 3 separate Google accounts and am able to download each time, once I signed in.

Thank you. I was able to download the .world file from that link.

Could you tell me why I couldn't play my previous saves of that map after I used your fixed sunlit tides.world? I also found all maps I replaced with your fixed official maps in \Documents\Electronic Arts\The Sims 3\InstalledWorlds, I can't play the previous saves normally and game reports error 12. But I applied your other fixed official maps like islaparadiso.world in \Program Files (x86)\Electronic Arts\The Sims 3 Island Paradise\GameData\Shared\NonPackaged\Worlds, the game runs fluently and I can play those previous saves without problems.
