Hi Eugene,
Welcome to Box Community and glad to assist!
To fix your issue, please reset your Box Drive application manually.
- Exit Box Drive (if it is running). If necessary, use Task Manager to end the Box.exe process.
- Ascertain whether any files exist in C:\users\rUSERNAME]\AppData\Local\Box\Box\unsyncedFiles. These are files that have not been uploaded to Box. If these files do exist, and if you want to keep them, copy them to any location outside of C:\users\rUSERNAME]\AppData\Local\Box\Box\ (such as your desktop). Proceeding with the steps below deletes these files.
Delete this folder: C:\users\sUSERNAME]\AppData\Local\Box\Box.
From RegEdit, delete the registry entries under HKEY_CURRENT_USER/Software/Box/
Box to clear Box preferences.
Restart the Box Drive and follow the prompt to log back in.
Hope it helps!
