Reinstelation Cubase 7 Elements

This is my first post, so welcome everybody.

I have a problem with reinstalation the above.
After HDD crashed completly, I have installed new one, new system etc.
When installing Cubase I’m asked for activation key, but this product is alredy registered on Steinberg webside.
How to register that again (remove previous licence).
I have box edition, with CD.

Thanks in advance.


Yesterday i read knowledge base several times but missed that. Maybe it was too late.
Anyway will check in the evening.


Thanks a lot.
It’s working now.
