Don't update Auto Tune licenses to iLok if you need to open older or recent projects

I have trouble opening older and recent projects with Auto Tune instances after updating my licenses from WIBU to iLok. Upon opening, DAW just stops loading at the track where there's Auto Tune and immediately crashes. Reached out to support hoping they have an answer, and they did, but none of it is working. Now, I'm just sitting here hopeless on how to proceed on an important project which I've been working on since last month. Hands are tied.
