Hi Brittany,
Sorry for the trouble here! In fact, I just saw one other thread come in this morning reporting a similar message in a similar situation.
Looking at your account, this is the website I see that is currently registered with your Events Calendar PRO license: http://www.stmarystudentparish.org
Just to confirm: is this the correct site?
If it is, will you please take a screenshot of your Events > Settings > Licenses screen and share it with me here in a private reply? I’m hoping that will give me a good idea of where to look and see whether I can replicate the same issue on my test site.
Thanks,
Geoff
