First of all, yes I did read up on the thread of other people with this same issue. I uninstalled everything and reinstalled several times. I followed the directions carefully on the suggested “nuclear option.” But when I try to open SGP, the “wait a minute” wheel spins for a second or two, then disappears. Nothing else happens.
As background, I had downloaded the trial version many months ago but never really used it, allowing it to expire. It didn’t open before I bought the full version (which I did yesterday) and the full installed version does not open now. I am using Windows 10. Any suggestions would be appreciated.
