I was using 2010 version of office and had the toolkit to activate it. Dunno what happened but it no longer works and i installed 2013 version of office to use the trial as i need office for my business. Now 2013 has run out and when i try and use toolkit 2.4.1 it says KMS failed??? I have no idea what KMS is despite attempting to read up on it. I have read several posts on here and have no idea what im reading about? I just need to activate office as my work is getting so behind and i cant move on until i can use it again, can anyone explain how to activate it please? I have sat here for 3 hours yesterday and 2 hours so far today, its doing my head in now and i cant deal with it anymore. Any help will be very much appreciated.
