How long have you had your key?
Did you buy Defraggler on it's own or as part of the 'Pro Plus' bundle?

If your key expires then your Defraggler should simply revert to the free version and continue to work exactly as before.

Without a licence key you will lose priority support and automatic updates.
You can ask for and get support on this forum.
As Defraggler has not had an update for 4 years now that shouldn't be any great loss either, and you can still update manually if an update is released.

Basically buying the pro version of Defraggler is simply paying for priority support and automatic updates.
(Many of us think that isn't worth the money).

i didn't have a key, as i was thinking of buying a copy (or year in this case)

am i right in remembering you also got some extra features like automatic defragmentation or were they made free?

after buying defraggler pro for one year can i still use the key given on future releases or do i need to buy another year?
