HELP, URGENT! Mulab plugin becomes unregistered. Gig tomorrow night.

This isn't the first time this has happened.
I should have raised it before.
I've a gig tomorrow and every song uses Mulab plugin at its heart.
I have 2 near identical systems that I can switch between should one crash.
I call them Green and Red.
Yesterday Green lost its Mulab patch for song 3. It lost its vst snapshot which loads with the song.
It reverted to an init patch. It never told me that it became unregisted (though iit did in July when it happened before) I loaded the saved Mulab project for that song and it recovered. I saved the vst state and it loaded fine today.
However Red system has just done the same thing on Song 3. This time it's telling me it's unregistered. (when this happed in July I put the key back in, reloaded the stored Mulab project and all has been ok until yesterday)

I'm using Mulab plugin v9.1.28. Both systems are not connected to the internet.
So, the first question is:
Does Mulab plugin check keys online every few months?

Could it be that you only inserted the initial user key but not yet your personal user key?
Anyway, don't publish any user keys here !!
Lets handle this privately via email.
Please email to

No, not at all.

Thanks for the swift reply.
It is a full personal key (I believe).
I've used the same procedure as I did back in summer to get it up and running again.
I'll email you.

It is a full personal key (I believe).

An initial user key contains "Initial User Key".
A full user key contains your personal name and email addres.

Anyway, lets indeed handle this privately.
