I use a VPN service, with OpenVPN installed, and for the past 10 days or so a registry error box has been showing on computer startup. See the screenshot below. Otherwise, the service is working fine. The VPN service's techs (Private Internet Access) suggested a few possible fixes - running as admin, reinstalling, checking exclusions on security software - but none have stopped it. Neither did a system restore at the time. I did a complete uninstall with Revo Pro (medium setting) and then reinstalled, a few reboots in there, but that didn't fix it either. So we all are at a loss. Any suggestions? Win 8.1 Pro x64. Thanks,
