Cannot activate after clean install

Hi there
I did a clean install on my iMac after a crash. Now I cannot activate parallels desktop 13 again. From Parallels itself I can't get any help, because I do not use Facebook nor Twitter. As described I shoud see a button "activate on this computer", but there isn't such a button.
What can I do to use parallels desktop again on the same Mac as before the crash ??

 

Hello,
we made some changes with your Parallels Desktop 13 license key.
Please check the activation issue and let us know how does it work for you.

 

Thanks a lot
I could reactivate Parallels and it works fine now.

 

Glad to know! Thanks a lot for sharing your results with us!
