Thanks to you both! It's been so long that I didn't renember where I put it (I've owned B4a since v2.20). I got a new machine --the previous one died -- and I have to pull the drive to search there, but have to wait until the external enclosure arrives. As I recalled I copied the attached license to the main install directory. I wasn't sure I still had the email, but I found it. I'm writing this on my tablet and will have to wait to sign in on the new machine to copy the license to where I normally keep the "working" copy. Thanks again.
