If it does not help, please send us the diagnostic logs from both the machines in question by going to the main menu button and choosing "Diagnostic", use "Send to Support" button there. The logs will be sent to our support team automatically. This will help us diagnose and troubleshoot the issue. Please add "Logs for Harry from forum" to the issue description.
