The error may be caused by an update or a non-standard shutdown of Windows or other non-standard operations. In this case, the file Filemanager.xmlthat stores the data structure is usually broken. In case you have Drillbook 2.9.3 and above version installed, there is no worry that you will lose your date.
Try to uninstall the DrillBook first, restart the PC, download the latest version from the website, reinstall and run the DrillBook. If the error persists, proceed as follows.
Do not run the DrillBook!
To get the data operation, download and use Total Commander, see https://www.ghisler.com/
In Total Commander, allow hidden files to be displayed (Configuration – Options – Display – Show hidden files)
Find the path to the DrillBook data folder: c:\Users\<user name>\AppData\Roaming\Euro4\Drillbook Profesional StartUp\220.127.116.11\Data\
Back up the whole Drillbook Profesional StartUp folder!
Open the Backup folder and make sure you have backup configuration files, such as FileManager_0006.~xml
Compare the file size and the last file before any major resizing will be the last undamaged backup, copy this file to your work directory anywhere on your hard drive.
Back up the (damaged) file FileManager.xml from the Data folder to the same location. You can check if the file is broken when you compare the size. Broken FileManager.xml will be smaller then backup configuration.
To Data folder copy the last undamaged file, in this case FileManager_0006.~xml, and rename it to FileManager.xml. This will overwrite the original, corrupted file.
Run the DrillBook and activate it.
