I have an old version of daynight

Ho, I have a previous version of the daynight templante, yesterday it was offline from the host for not having an updated version. If I buy the new version, and install it, will it solve the problem?
I did not make that purchase directly, but if buying the new version is the solution, I do it. I need advice.
Thank you

Definitely you should to purchase license from your own account. purchase new license and update the template to new version will solve your issues or not! I think your hosting can tell you better as you mentioned your site was offline from the host. Also you can contact template author for any technical query.
