So if the A7 Pro key works for A6 Pro, I would still need the A6 professional WED, SED and MED exe's right?
I could download the A6 upgrade using the A7 key is what your saying right?
I'd contact Conitec about this, because if I recall correctly you'll have to ask JCL for the files.. if it's still even possible.
The A7 key is a different kind of key than I've got for A6 pro by the way, but I wasn't one of those people buying A6 when A7 was already officially announced.
