  1. Using your file manager (Windows Explorer or Mac equivalent) browse to your user diretory
  2. Find the file called 'AppData'. If you do not see the folder, it may be a hidden file.
    Windows directions to show hidden files:

    2. Select 'Folder Options' and then the 'View' tab
    3. Click the radio button for 'Show hidden files, folders, and drives' under the 'Hidden files and folders' option.
  3. Inside the AppData folder, find the folder labeled 'Roaming'
  4. Remove the folder labled '3MCloudLibrary' in the Roaming directory
  5. Close Windows Explorer and restart the application. You will need to reenter your libary information.

If this problem occurs frequently, uninstall the 3M PC App completely using Windows add/remove programs. Then follow the steps above to make sure that the <username>/AppData/Roaming/3MCloudLibrary/ directory is also removed. Reinstall the PC app and log in as usual.
