Unable to verify licence for MS Office after Norton install

Hi!

I have renewed my Norton 360 and as soon as I downloaded it, I could not use any of application of MS office.

I cannot open my emails or use Excel. It gives me a message that the licence cannot be verified and advises to repair the program and then it closes it down. I cannot even read my emails.

I tried to repair and also re-enter the licence number and all without a success.

Please, help.
