Photoshop CS6 - Pop-up pushing to buy extended version, what happen if I don't do anything?

I have a licensed version of Photoshop CS6 standalone.

As what happened to many Photoshop users, I suddenly get this pop up with 5 days left to buy the extended version.
(Probably the CS6, or CS6 Extended, can't be purchased anymore)

Help>Deactivate is greyed out.
Except for un- and re-installing Photoshop, I have not found a good solution for this problem.

Now I could to all that, but I wonder what happens if I just don't do anything?
Point is that CS6 is running as 'Extended' version now.

After the 5 days, will it then go back to the standard version?

Thanks!
