OS: Windows 7 App: Excel 2013

After logging into Trello on the add-in I get this error and cannot import any data. No boards are visible.

I removed and reinstalled as well as revoked and restored privileges from Trello

Once i have installed and attempted to login, how do i logout and login as a different user?

Same here. I believe the problem exists because the boards can't be retrieved.
