Your Pro payment entitles you to updates for up to 6 months. You can download whatever stable releases or Beta versions are released within the 6 month period. But it's up to the user to save & back up all installers downloaded...LW doesn't keep a backlog of old installers for download.

dragonzero, you've posted about this before.

Of course you won't be able to download updates after 2 years.
