Hi,
Not sure if it's coincidence or not, but after installing the X3c patch, my Waves 9 licenses were no longer found. Very strange, it was working fine just an hour prior. 
 
If anybody else encounters this, just rerun waves license center - it asked me to download the latest license center again (even though I already had V9), but be sure not to select to upgrade any VSTs, as you'll have to wait for the entire Waves plugin suite to download (even if you only own one of them)
 
I'm sure many of you longtime Waves users are used to this, but personally I find their setup completely absurd.
