Hey @oginecka50 , welcome to the Discussions forum I understand you've found the New World soundtrack to start playing before it is actually unlocked - that's really unusual.
I've gone ahead and reported this to our teams so we can have a look at this issue from our side. In the meantime, can you do a couple of things that will help us further with this for me?
First, please check our troubleshooting guide, which contains a few steps that make sure the game is running in the way we'd recommend. In particular from the guide, please make sure you are running the game with administrator rights, you've verified the game files, you've got your Windows install fully updated, and you've (at least temporarily, for testing) deactivated all background programs.
If the issue then yet persists with your save file, can you send it across to us? The file can be uploaded to the file-sharing site of your choice, so that you can link me to it here in the thread. You'll find the save file here: %userprofile%\Documents\Anno 1800\accounts
Please let me know if I can clarify any of these steps, and sorry for the inconvenience while we look into this. Let me know if you've got any questions
