If you have a Live Access user who shows as suspended in the Live Access user list but you did not suspend that user, you'll want to go to KC Desktop, File, Employees, locate that user and see if they are marked as "Inactive" which will be a red color. 

KC Desktop Employees section showing Inactive:

If this employee should NOT be inactive any longer, simply select the employee in KC desktop and over to the right uncheck the inactive button. Save changes.
