Database Version Incompatible

If you see a Database version incompatible message (or similar) when starting WonderPen or opening a library, it usually means the database has already been upgraded by a newer version of WonderPen, and the older version you’re currently using can no longer open it.

This message can appear for the following databases:

• The configuration database
• The user database
• The library database

Resolution

Update WonderPen to the latest version, then open the library again. Don’t keep retrying with the older version, as that may make WonderPen mistake the library for a corrupted one.

If you use the same Cloud Library across multiple devices, or sync the same Local Library, try to keep all those devices on the same or a newer version of WonderPen. Once one device upgrades and opens the library, other devices on older versions may no longer be able to open it until they are upgraded to a compatible version.

Caution

Don’t manually edit the database files inside a library, and don’t overwrite an upgraded library with an older version. If you need to roll back, back up the current library first, then contact support or restore from a backup.
