Hello Neil,
Thanks for using our plugins and welcome to the forums!
That is an excellent question!
You are right, you can use the license on 10 different sites and you can have 100 imports daily combined.
I guess you have entered your license key on both sites and it shows it’s valid.
What do you see when you go to Events > Import? Can you choose any of the import options?
Also, can you please check your Event Aggregator Status Information for both sites? It is at the bottom of the Events > Help page. It should look something like this.
We’ll get down to the bottom of this.
Cheers,
Andras
