One step update hung after Fidelity reauthorizaion

Got the notice that I needed to reauthorize my Fidelity accounts today. Clicked thru all the steps and now the One Step Update hangs Quicken, showing the Fidelity accounts completed and Processing Data. That's where it hangs and the little circles just go around. Had to kill the process thru Task Manager. I've logged out and in, and rebooted. No change. Quicken is unusable for me until this is resolved.
