Thanks... but an hour and a half later after there is no solution.  It's hard to have this kind of time sink during tax season.  After an hour and a half, I had to go to the door and meet a client.  I put my partner on and they wanted him to reboot.  He did not.  Wasn't sure if I had critical work open.  They said I would have to call back, which means I'd have to start over with someone else.  A reboot wouldn't have helped.  We tried doing an e-signature request from my partner's computer with the same error message.

Has anyone else encountered this error on an e-file signature request?  Any info is appreciated.
