License regularly bought does not work anymore on same PC

Hi Guy,

I've bought a license on january 20, 2020 installed and used it to manage first race with 43 drivers into a new PCLC installation; everything went well at that time.

Unfortunately the global pandemic forced us to dismantle that installation and to store track, computer and all the other thing in a safe place.

Now we are restarting in a new place with same track and same PC.
For a reason to me unknown PC Lap Counter when started is asking me again the license; I've collected the original eMail I've got at purchasing but the activation key is not accepted anymore from software.

As a proof of my position I've in my mailboxes collector on my PC:
- the original email related to payment to ShareIt! eCommerce
- the original email I've got back reporting the Activation Key

We'll have the renewed club startup event on Wednesday afternoon so I am a little under pressure.
What is the best thing to do to have my PC Lap Counter installation to work properly?

UPDATE 26/09 time 19:30: I've discovered the existing procedure and have written an mail with infos requested.

Regards,
Gianni Sandigliano
