License issue

Just bought the whole deal, got a license, downloaded the software with the link, launch it.
Getting a message for a registration key, fine, I have my license. I tried to enter it in the “activation key” question – Activate.
Error message, tried it again, another error message. Tried it another time…
And now, It’s telling me I’ve used this too many times… 🙁
Well, is this the end of XPresspads for me?
