Not able to backup to external hard drive. Error message.
I previously used PSE 5, 12, and 14. When Mac upgraded to Catalina, I got a trial version of PSE 18. Before it expired, I bought PSE 2020. It works but when I try to backup catalog, I can't get it to complete the backup. I choose the catalog (only have one), choose full backup, choose external HD, and after a minute of preparing, I get an error message. I can't copy/paste it so I will type it in below. The only thing I notice is that it ends in pse 18db. Do I need to somehow get rid of PSE 18, even though I'm using PSE 2020? I have read through 15 pages of questions and have not found anything exactly like this. I'm not a computer geek so please type slowly. 😉 Thanks.
