Could you post a link to that thread please?
Edit: Never mind,
here it is
Another edit: I think the problem is that this file Union Cove _0x00000000ExportDB.package is missing in the save folder.
All other saves have a file like that, except those from the latest version of UC. Copying this file from an older save a renaming it as it should be, made the save show in the main menu, but with an error message. Makes sense, since it contains completely different data from other sims.
I posted a similar response in the new thread about it, where I will continue about this problem since that thread is specifically for this problem. I sure hope you guys can find the solution quickly!
Another edit: Closer to the solution!
I think I found the source of the problem and I can load the game yay! Please see
this thread. I think this might help you too, Saturn.
