Continual pop-up in Word 'Connecting to Office.Microsoft.com' asking for credentials

Starting today when running Word, I am continually receiving the ‘Connecting ....’ message below. I have been running Office Home/Student 2010 for the past 4 years and have changed nothing in that time. I have tried repairing Office but a file is apparently missing. I have removed all entries from Credential Manager and I’m not running a Proxy Server.

What could it be?

Thank you.

This problem may be caused by the translation service crash. Please use another service site to replace the current one.
Here you go:

3. Change both QueryPath and RegistrationPath from http://office.microsoft.com/Research/query.asmx to  http://rr.office.microsoft.com/Research/query.asmx
4. Restart the Word 2010.
