Hi all! I know the question of no rearms left have come up repeatedly in this forum but I hope you guys can help. I have searched through the forum and I can't find the solutions for my specific situation. I have used up all my rearms and I had no idea that I should've kept renewing my rearms. My situations: I am currently using MS Office 2013 Pro Plus under Windows 8.1. Rearm count is 0 in MKT Red bar across the top of office with "Product Activation Failed" So my questions are: How do I get my rearms back up to 5 and activate my product again? I do not mind using earlier versions such as Office 2010 as long as I can use it without problem, so can I solve this problem by rolling back to earlier versions? If I do need to uninstall my office, what tools should I use for a clean uninstall? MKT or are there others? Thank you guys!!! any advice is welcomed and useful threads or links would be great too!
