Ok, I found two directories in c:\users\dane\AppData\Local.
The new one appears to be "VNM Leisure yacht"
The old one appears to be "VNM Leisure yacht V0.0.1c_mappa"
When I copied the old one and renamed it "VNM Leisure yacht," the game saves show up in the new version. When I tried to load any of them, however, I get an error. I can't manipulate the error message window or copy the text from the error message. I took a picture but the file is too big.
When I click OK on the error message window, the program screen goes black and I need to shut down the program.
