I recently purchase a second hand licence for an Adobe Master Collection CS6 upgrade for my existing Adobe Master Collection CS5 licence.
This seems to have worked well.
However, when I go to my Adobe account and try to register the new licence I get a message:
"This serial number is already in use."
Is there any way I can resolve this?
Many thanks for your posting - that was very helpful.
The instructions you provided specify that a Case Number must be provided for the transfer to take place.
How do we obtain a Case Number?
Looks like filling in and returning the License Transfer form gets you a case number, but I don't know. Like most of us around here, I am not an Adobe employee.
