I made the mistake of downloading version 2.2 and updating the java only to realize that none of that is compatible with my old MacMini running macOS 10.13

im a novice at this stuff but it worked perfectly before. can anyone help with this please.

If you have Time Machine you can just roll back to a point before you changed things, that would be simplest for you IMO.
