Hi Tim,
Welcome to Box Community and glad to help!
Please reset your Box Drive 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\\USERNAME]\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\\USERNAME]\AppData\Local\Box\Box\ (such as your desktop). Proceeding with the steps below deletes these files.
Delete this folder: C:\users\rUSERNAME]\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.
You may restart your machine as well and once it booted up, please re-launch Box Drive and login to try again.
Hope it works!
Thanks for the detailed steps, Rona! I went through all those, and by Jove, I think it's worked! :o)
I did find when deleting Box\Box that my system kept flagging I needed enhanced permissions...so I went into each subfolder, deleted contents, then deleted the parent folder, and that worked smoothly. Other than that, impeccable instructions! 
I've tried these and no luck. Can you send a screenshot of what this should look like? I've rebooted, tried to reinstall Box Drive and still no luck.
