Not too long ago I changed gmail addresses.  How do I change the login account for the google contacts tab?

I can't find any option or command to change the settings.
Now, I could edit the ini file, but I can't encrypt the password there.
I tried deleting the .res file and the .csv for google contacts, but it didn't give me any new sign in box.

When I push the refresh button, it just says "authentication failed (200)" and that's it.

In the google contacts toolbar, there are buttons for refresh and clear, then there are two separators where it looks like a button should be but isn't.

Google Contacts has plenty of room for storing information for all of your friends and business associates. But sometimes, you just don't need all of it.
If you start deleting entries and make a mistake, the information isn't lost forever. Instead, it can be retrieved with the restore feature nestled in the Google Contacts menu. Here's where to find it:
Step 1: Open the new Google Contacts website in your browser. 
Step 2: In the menu on the left, click More and choose Restore Contacts.

Step 3: Choose the appropriate time frame to include the deleted contact and then click Restore.
Your deleted, merged and edited contacts will all be restored to the point in time that you chose.
