When I try to erase my authorization of my computer it keeps saying, "unable to erase authorization. Try again after sometime"

I was able to delete activation.dat file on my mac easily.  But after deleting and re-installing ADE, it shows as being authorized already (STILL), even though the .dat file was removed. VERY FRUSTRATING!!!!

Thank you, Chirag!  Had to go in the registry to get rid of my authorization.  This happens every time I update Adobe Digital.  Do you know why?  Shouldn't the software update the authorization at the time you update?  I am no computer techie but I've had to learn on my own mostly because of issues with Adobe Digital.  Just wish I understood the "why" of things, you know?  Anyway, thanks again!
