Guys sorry for bothering you but after a couple instalations of Office 2013 Pro, I managed to get the message that it was correctly activated with Microsoft Toolkit 2.4.3, donwloaded from here. However when I open the different Office apps, they do not show the info "activated" and on the contrary Excel from times to times doesn´t allow me to save the worksheets saying it has not "been activated". what can i do? Thanks
