Hi, I have just run an update to my WordPress today (26 April, Australian time) and it is saying my licence key has had too many installs, this is definitely not the case, I am only running Event Tickets Pro on this one site and my licence is not due to expire until January 2018.
I have seen the other posts reporting a fix for this but it does not appear to be working for my site.
Worth noting in my Events > Settings it says the key is valid in green.
========================
