Sorry for the inconvenience. You are right, has a bug in 1.10.0, and we will fix as soon as possible. You can't use the new database version with older program version. We have to change the database structure, otherwise it is not possible to add new features. But new older program versions can't read the new database structure.
It is also not possible to open the database in other program. Read more in FAQ why. Here is the link:
