Hello. I needed to reinstall windows on my computer. My update protection suscription ended on 12 october 2018 but right now I'm not able to purchase the new software until mid december. 

After reinstalled windows I reinstalled Website X5 Evolution V 16.0.30 which is the version I have and activation was successful. Trying to activate V 16.3.1 update does not work, it tells that activation was successful but after clic on start it opens the activation window over and over.

I have projects made by 16.2.1 and therefore I cannot open them. Is there a way to download V 16.2.1 and will I be able to activate it? Or am I forced to purchase the new version 17? That's the only option I have to purchase in my offers section. I'll be waiting for some answer. Thank you very much in advance.
