How can I change the Evernote account that my TuskTools Calendar is attached to?

Follow these steps:

1. Exit from TuskTools Calendar.

2. Right-click on the TuskTools Sync icon in your Windows system tray.

3. From the context menu, select "Log Off".

4. A login dialog should appear; enter the information for your new Evernote account.  (It's recommended that you check the "Remember me on this computer" checkbox.)

5. You'll then see a dialog informing you that TuskTools is performing an initial sync with your new Evernote account.  When this sync is completed, you'll see a notification balloon above your Windows system tray.  At that point, you can launch TuskTools Calendar with your new data.
