Can you see, if I have bought FredoSpline now?

I bought Basic Premium Plan and my user ID: 1277920.

According to my paypal, I made the purchase at 10.58 today.

HELP! FredoSpline license does not work.

I have not received any email but apparently, a license is on my computer but when I try to validate it, I receive a message (msg_validation_error Request to Sketchucation = ERROR_FO8 )

When I follow the PDF, then I'll have to pay again 15 dollars for a license.

What to do?
