Yeah, this is so weird. I'm exactly where I'm supposed to be:
C:\Users\*username*\AppData\Roaming\Kodi\userdata\keymaps\mouse.xml

I downloaded mouse.xml directly from your google drive. I should note that I'm using the T3 with the microphone, so that could be the difference? I dunno, I'm kinda at a loss here.

I have both versions of the remote, microphone and without. Both work for me.
Maybe a stupid question but have you accidentally pressed the TV button and put it into IR mode.
