Just a short heads up: Currently Apple’s servers aren’t on top of their game and downloading reports can take some time or completely time out.

Just re-try it a few times and ignore the “unexpected login error” message Suborbital Reports is displaying.

If you can’t get it to work there’s another option: Log into the iTunes Connect page and download the daily reports. You can import those files then via “File -> Import Report Files…” in Suborbital Reports.
