Quite often if you try to copy and paste the details into the registration it will not read them properly and tell you the details are wrong so l actually went back and typed the details in instead of pasting and it worked for me, so try it.
I downloaded and installed WordMate a couple of days. Everything seems to install just fine, but when I opened Word 2016, there was no WordMate tab. I just went through the whole process again. I got a couple of messages saying the installation had been successful, but again their is no WordMate tab. I have an Add-Ins tab, and when I click on it it shows me two add-ins, but WordMate is not one of them.
