I have v1.1, but I just went to the Sweetwater website and see v1.3 is available. However, as users experiences last year, I don't see a link to update my already-purchased version; I only see a way to re-purchase (which, of course, I don't want to do). Sadly, I can't find the email from my original purchase, but it does appear in my order history.
Any advice, anyone?
EDIT: I found a link in the description column of the Sweetwater online invoice. Clicking that brought me to a download page where I was able to download v1.3. I'm leaving this here in case anyone else runs into the same issue as me. :)
