Opening manager files

Greetings. I am new to Manager. Have been using it since February this year. When I created my business I saved a backup in dropbox and used to open it directly into Manager. Recently I reinstalled the programme since I had issues with my computer. After the reinstall, I have to import my business every time I click on it. I have done everything in my power to come back to the old system where the business opened directly, but haven’t succeeded. Can someone tell me how to do that?
Thanks

If you search the forum, you will find that this has been flagged as a bug and is awaiting correction

Regardless of the bug that currently exists, there is no reason to do things the way you are. If you want your data permanently available via Dropbox, you should change the application data path. See the Guide: https://www.manager.io/guides/10348.
