I had mentioned this earlier. I went back to SGP 22.214.171.124 and everything works.
Thanks for the suggestion. I'll try that one tonight. I was on my list of other things to try.
Virus software? I had a problem with earlier SGP versions not running because of Avast.
I guess it could be, but would expect it not to work from first install if this is the case. It was working, and only has stopped after a system crash. And there it nothing in the antivirus logs showing me that something from SGP is being blocked.
