Duo - user has not been authenticated

Hi newbe here. I have the Duo and all was working great. Now when I use Raidar I get the following message "The operation being requested was not performed because the user has not been authenticated" This may have been when I reset my password. Can someone please tell me how to overcome this. I know I can put it back to factory settings but I think this will lose all my data on the disk.

Any help greatly appreciated.

Thanks in advance
