This is so damn frustrating. I'm in Canada and all I want to do is upgrade from 5 to 6. The website either defaults to buying CC or puts me in the store for Southeast Asia. Once I change the location to Canada, there's no longer an option to upgrade. I tried their chat "support" and they told me they'd send me a phone number to call tomorrow. Can anyone tell me how I give Adobe my money?
I don't live in Canada, but I switched my region to Canada, and I'm not having any trouble purchasing an upgrade.
If you click on Buy next to Photoshop Lightroom, and then on the next screen set the dropdown menu to Upgrade, and set the rest of the dropdowns appropriately, voila!!!
Had a hell of a time getting to the correct page, but when I did your instructions worked, so thanks very much for that!
