Piracy

I apologize if this has been answered elsewhere - I haven't been able to find the info I need. See, I've been trying to get a working installation of Office (well, just Word, really) for a long time now, but every single time, I run into a problem: it slips into reduced functionality mode after varying amounts of time. Everything's activated, everything's working just fine, and then boom, RF mode. Sometimes it happens over a few days, or even a couple weeks, but it happens at some point. Just recently, I had a fine working copy of Office (Word) 2007 for a while, but then poof, it went into RF mode the other day. I've been dealing with this shit no matter what version I use. 2007? RF. 2010? RF (Just happened now as of this post). 2021? Opens up documents that worked in every previous version IN RF mode. 2013, 2016 and 2019 all lag so much that I can't even do much to see if they'd slip into it too. I would like to finish a project I'm working on to get me through the pandemic time, but it's not really looking like I can. Is there anyone here who can help? I've used every concievable method of activation (I used to post on My Digital Life, but nothing there helped) and I've done them all exactly as I'm supposed to. But KMS_VL_ALL, etc doesn't seem to do anything for me. I made all the necessary AV exceptions (I just use Windows Defender) too. And I'd rather not use one of the "alternatives" as they just butcher the document upon opening. Any help that can be provided will be appreciated. I hope everyone here has a safe, happy and healthy New Year.
