Somehow, Pitch n Tine 2.5 was installed on my system, and I need to go back to ver 2.1 for My ILOK liscense to accept my plugin. I do not have an account with Serato, but have a valid liscense on my ILOK. How can I get a proper Install of my legally owned copy of ver 2.1 that I purchased many years ago.

My information is:
Michael Warfield
10006 Palms Blvd #305
Los Angeles, CA 90034

In the intervening years, most info has changed but that above. I can return the original disk for a replacement.
