why am I pay montly for Adobe when I purchased the very expensive Disk for Pro?

I dont expect anyone to answer as Adobe cant seem to answer.  I purchased "pro" becasue I loved using it where I had worked so I wanted it for my home.  It cost ($800.00 or $1000.00) at the time; Very Expensive but worth it.  Some time ago (? when) Adobe just didnt work anymore and I started getting messageages that (In a sense) I would have to "rent" the rights to have access to my documents on my home computer.  $50.00 + a month.  so ~ $625.00 a month.  That I have been paying.  In effect, buying another set of Disk, every year.  Currently, just got off chat do to Billing Issues and feel like a Hostage.  What was that "Ransom" ware virus called? Ransomware?  So all of my documents are held hostage, and the program as well unless I pay the montly Ransom.  And I dont know why?  Other than agreeing to it; in a panic.  So that's It; currently waiting for the "Adobe" people to accept my payment or lose access to everything.  Happy Halloween.
