Well I have Zorro S since 2015 and now we have 2.xx
I get the message:
Update period expired.
Please extend or revert to previous version.

So, could anyone explain what is the meaning of this annoying message?

where is Lifetime license and what for?

On one hand, "Extent" means to pay more and ... not, thank you.
On the other hand, "revert to previous version" means "you must eat all the known bugs" and ... again I have to refuse friendly. This bussiness doesn't allow this kind of frivolities, unless for me.

Lifetime means lifetime not "lifetime until 1.99"

Well It was nice while it lasted.

Nonetheless, I would like someone to clarify these points

Thank you.

You must be a time traveler when you got a "lifetime license" in 2015. We had no lifetime licenses back then. In 2015 you got a license for Zorro S 1.4, which included further Zorro 1 updates as described in the FAQ. The update extension works for those licenses too.

You must be a time traveler too,
Please, check your e-mail when you send me my S-licence on 10-11-2015 17h01

Here it is the e-mail

I actually am a time traveler. See this link.

"The Zorro Sponsor module (Zorro S) includes a lifetime license for unrestricted trading with Zorro. It also unlocks the sponsor features in all Zorro 1 versions: no account limits, multiple instances, generating executable systems, live trading support for all MT4 brokers, and a lifetime subscription of all Z strategies."

Your Zorro S license is still valid for Zorro 1. You may use Zorro 1 for up to infinity years.

It would be nice if oP group left a legacy link to the final Zorro 1, though.

Better yet, now that we have the 2-year policy, might as well leave up all of the links, one for every release.
