The transaction log (.tlg) and Network Descriptor (.nd) are QB program files containing recent transactions and the path to the data source, respectively.

• Open your QB folder using a file explorer and look for .nd & .tlg files inside the folder.
• Right-click both files individually and select the Rename option in the list.
• Add ‘.old’ as an extension to both the files (.nd & .tlg) and save them on your system.
• Launch the DBSM and navigate to the Scan Folders tab.

• Wait for the scan to complete and retry opening the data file in QBDT.
