Hello, Customer Support was unable to provide me with a direct download link to the immediately previous version. I accidentally updated to AME v. 13 without realizing its incompatibility with my hardware and Mac OS. Customer Support provide me with 12.0, but this was not the latest version I had previously been running in a stable configuration with Premiere Pro 12.1.2 (Build 69). I cannot update Premiere Pro beyond this build due to age of hardware and OS. Thank you for your assistance.
