Activation error

Hi,
I already have one of your products (WP File download 1 year) and was looking for the Table Manager.
I wanted to test it (the free version) before buying in my local instance. But the activation was canceled with errors.
Therefore I cannot test it, and I'm asking if the "pro" version has the same problem.
Here are the message after the activation trial :
