Steam Activation Error

Unfortunately for me my computer broke down a few weeks back, so I decided to purchase a laptop. However, when I try & install FM09 through Steam I get the "Unlock key is already active" message. I have tried this fix but to no avail;

Error: You are receiving the Error ‘Product Key already Active’ message

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 program and retry activation - ensuring you have 'verified' your key using the following website: http://keylookup.fm2009.softanchorinsight.com/

7) You should now be activated

Yet when I run the game again it takes me to the SoftAnchor key activation bit again and still comes up the same. My laptop is running on Vista, has enough space etc, so what could be the problem? Any help would be much appreciated.
