Activation code issue with Wavelab LE 10

I recently purchased the UR22C starter pack with free cubase AI and Wavelab LE. My cubase is all good, but I can’t access Wavelab.
I have downloaded the software and also used the access code provided to get my activation code.
Unfortunately (probably user error initially) the software is asking for an activation code and tells me that my code has already been used and can only be used once - but I’ve never successfully been able to access the software.


I would be intrested in the answer to this question too
