I have similar problem here. My Macbook Pro logic board failed and needed to be replaced. I reinstalled Parallels after data migration and its asks for activation, but when I entered the activation key, received this error:
Your product activation key reached its activation limit and cannot be used to activate Parallels desktop, Please use a valid key or contact the Parallels team for assistance.
This activation key was on this computer before computer crashed, would you please help me for this?
Thanks,
Kevin
