Your plugin is a very good one. I tried the demo and I decided to buy it.
So I did it.
But really, it is very complicated to install it.
I have tried to install it through WordPress: no way!
I have unzipped it and tried to install it using the folder wp-content:plugins: still no way.
I have tried to log in to my account after several time: the error message told me to try again with 24h. What is this?
I do hope your will help solve this problem now.
This is my API key : 7011-11403-Cmi5%$CC
I look forward to hearing from you.
