Trial version teminate


I have activated Spectralayers PRO 7 - trial version .
Meantime I bought and instal full version of Spectralayers Elements .
Because the instaler is the same for both version ,
in my PC still remains PRO version (trial).
I would like to stop a PRO version trial and start to learn an Element version.
Reinstalling does not help.

Can anyone advice me?

Thank you !
