microsoft office 2010 product key unlicensed

Im getting the microsoft office 2010 product key unlicensed message popping up when I open any of my office applications such as word, excel etc. I used the KMS activator to activate it when I installed it and everything worked fine until now. Is there a way of activating it again?? Thanks in advance guys, any help with this will be very much appreciated
Answer #1
Uninstall the activator you used and use office activator… I have used this on my office 2010 installation so I know it works 100% and have been downloading updates for months…

Version 2.4.9 is the version you need then just use activate button (I used this instead of installing autokms).
Hope this helps!
