Problem with activating again

I brought the game on the release date and it was running fine until 2 days ago when the key code screen came up and told me my trial period had expired. I put my original key code in and it said was unable 2 unlock request. My error was (-821) i came 2 your site and followed the steps 2 do the winzip thing and then double click on launcher. When i put my code in and waited 30 seconds it said activation failed with error -821 again. I dont know what 2 do now and its annoying. Please can you help.

You are receiving an Error [-821]

Scenario: Install and activate with activation code on Steam and it works then launch the game, SoftAnchor asking to re-enter activation code.

Fix: You need to delete the certificates and re-activate the game

1) On receiving the error, please uninstall the game

2) Please navigate to the following directory:

XP users: C:\Documents and Settings\All Users\Application Data\Sports Interactive\Football Manager 2009 Certificate

Vista users: C:\Program Data\Sports Interactive\Football Manager 2009 Certificate

3) Please ensure that it is the \certificate directory you are located in

4) Delete all content

5) Reboot the machine

6) Re-run the installation programme and retry activation - ensuring you have 'verified' your key using the following website: http://keylookup.fm2009.softanchorinsight.com/

7) You should now be activated

PS: You can backup your database and save game if you can't bear to lose them ..
