Adobe 3.0 Activation on a new computer

 I am, a long-time user of Adobe Audition -- for almost all pedagogical stuff as a cantor in a synagogue.  

Because of Coronavirus, I'm doing things at home that I didn't used to do at home.  (That sounds weird, but you get it. . . )  

This includes loading Adobe Audition 3 onto my laptop from the original DVDs .   Loaded it successfully.  It works beautifully.  But then there's that warning that my days are numbered. . . and attempts to register fail -- as Adobe no longer maintains the site or phone numbers for that purpose.   So. . .what's going to happen at the end of my 30 days?  Is there a work around?   Many thanks.
