Activation Trouble!

So I purchased the UR22 and with it came Cubase 7 AI, and I had it on my mac. But recently due to issues
I had to wipe my mac, but when I tried to reinstall Cubase it wouldn’t let me activate saying “This is already activated on another computer”!
I really wish someone would help me please! I would very much like to be able to use Cubase AI 7 again as there are some things I can only do on it!
Is there some way for me to deactivate Cubase 7 AI? I’m reinstalling it on the same computer…

The thread at the top of this forum…
has a section titled, requesting a new activation code…

I hope it works for you.
It did not for me.
