I moved Aperture 3 from older Mac mini to newer Mac mini.
I moved Aperture 3 from an older Mac mini to newer Mac mini. When opening Aperture (on the newer Mac mini) it asks me for name and sn. After input (it states "this is a upgrade sn) it wants the old sn. I don't know how to get it (I, long ago and several moves lost the original box). Apple store "knows" I am the legal owner... but doesn't help. I have tried to enter my Apple acount that stores such things (like it used to do) but that was a long time ago and I can't get there any more.
Any help would be greatly appreciated.
PS - Aperture 3 is working fine on my older Mac mini.
PS - Tried moving the pro app document to the library with no success.
