I recently installed SGP 3.1 544 (latest release) on my machine where I had previously used the terminal release of SGP 2.6. Since there seemed to be a few kinks with the software primarily around autoguiding, where it looks like PHD2 is telling SGP that it is guiding when it really isn’t, which resulted in blurry pics for me last night. I also upgraded from PHD2 2.6.8 to 2.6.9 at the same time, so I wanted to revert to SGP 2.6, which I’ve been using successfully, to see if I could isolate the problem further. I reinstalled SGP 2.6 over the top of SGP 3.1, which finished successfully, but when I launch SGP, it dies during license key check on the splash page, and the log contains the following error:
[08/09/20 07:09:07.251][DEBUG] [Main Thread] Licensing: Machine ID found…

I’m trying to avoid uninstalling SGP 3.1 first because I don’t want to lose my saved configurations. Any thoughts on how to get back to SGP 2.6?
