Latest version showing as "Trial"?

[Aidan]

The latest web versions of the game have reverted to the old free and full versions and the subscription sysem has been removed.

If you have bought a subscription recently it will be still be valid - see the "About" screen within the game - just keep using the game until your subscription expires.

There is no functional difference between the trial and full versions apart from the name and the fact that the full version has no expiration.
