I have seen this occur when the PC is not automatically running its smart card. To rectify this please try typing services.msc into your start menu and pressing enter, This will open up your services, Scroll down to Smart card and double click, If the Service status is on Stopped, Select Start, OK, Apply. You can also change the startup type: to automatic. This will ensure it stays on.
If this does not fix the issue please call through to our Support team on 1300 084 515 who can further troubleshoot the issue.
Cheers - Shaun
