If you are having this error when trying to log in, this means you have been locked out.
Simply close out of Forms Banner and ApplicationXtender.
Wait 15 minutes from that point, the user should probably give it about an extra minute or two just to be safe and avoid waiting another 15 minutes.
Then open up Forms Banner, and ApplicationXtender and you should be able to log in fine.
If you continue to receive this message, consult your department's imaging IT representative.
Always click the “Log Out” button when closing Application Xtender. Note: Power outages can also result in lock-outs.
