Hey CVIJR,
Sorry to hear about the hard drive crash — that's a rough situation.
David is correct on the license point: Premiere Pro 2019 is not a perpetual license. Adobe's last perpetual (buy-once) release was Creative Suite 6 (CS6) back in 2012. Everything from Creative Cloud onward — including the 2019 version — requires an active subscription to run. The software itself may have worked during a previous subscription period, but it's not something you own outright.
To get back up and running, here are your options:
1. Check if you still have an active subscription Go to https://adobe.ly/4bDB8bZ and sign in with the Adobe ID you used previously. If a subscription is still active, you can reinstall through the Creative Cloud desktop app.
2. If your subscription lapsed You'll need to reactivate a plan. Adobe offers monthly and annual subscriptions — if you only need Premiere, a single-app plan is less expensive than the full Creative Cloud suite.
3. Contact Adobe Support If you're uncertain about what license you purchased, Adobe Support can look up your purchase history and clarify what you have: https://adobe.ly/4gT3Au5
Unfortunately there's no way to bypass the subscription requirement — it's built into how the software activates, not the system requirements themselves.
I hope that helps.
Thanks,
Kevin
