As of 2026, is it still possible to deactivate Acrobat X Pro and activate o new computer?

In 2011 I purchased Acrobat X Pro and activated it on my old computer. Later on the old computer was dead and recycled without deactivating Acrobat X Pro on it. Recently I installed Acrobat X Pro and tried to activate it on my current computer, then it said  it was activated on another computer and I need to deactivate the other one first. I no longer have access to the old computer, what can I do now?

Thanks!
