Hi Antonahill,
do you still have the master0.lic-file that Jason sent you? Did you try to copy this one into the Animation:Master install-folder after fixing the permissions?
I am not sure if it will work, since you upgraded to Lion and the licence-file is likely keyed to the version of your OS to, so I am not sure about that.
If you tried that already, I am sorry but you will have to wait for Jason to fix this. Your licence-key seems to be already activated once and like that you can't activate it again without a new activation key. You will of course get one for free in your situation, but that has to be done by Jason and I am quite sure that he is not in the office on the weekend.
Sorry that you have problems with the activation. Hopefully you will get it fixed very soon.
If you upgraded to lion, make sure to use only the latest v16-version. I think older once can't be run on it, if I remember right. (I am myself a Windows-user, but I think I heard something about that, because Apple dropped compiler-support for the previously used compiler-versions with Lion).
See you
*Fuchur*
I can wait for Jason.
