Hi Sacha, bear in mind that you need to use your new Pro license key in the login field when activating Lumion, not your forum user name (If you try to activate it with your forum user name, Lumion will not know which of your two licenses to use).
If it still doesn't work, please delete myLumion.ppp in the following folder and try to activate Lumion again:
C:\Users\Username\Documents\Lumion 2
