a) Is your system up to date & otherwise behaving normally?
b) Have you run any registry cleaners lately?
c) Is your system clock accurate both time and timezone-wise?
I should have added yes, best to uninstall, then cleanup and then reinstall. You may have to reboot twice during that operation depending oin what is installed.
Yes did a McAfee clean up.
Not had problems before. I always do a restore point to. So could have done that but if not still would have to re install so went for it
Now re installed it and up to date and up dated it all ok again.
took 30 minutes.
OK, good luck ;-)
