Could you please send a verbose debug log (-dd on the wpa_supplicant
command line) showing this full sequence? I would also recommend running
a test with the current hostap.git (0.8.x) snapshot since there has been
some WPS ER fixes after the 0.7.3 release.

There is not enough information to figure out what caused this. I would
like to see the debug log and ideally, also a packet capture between the
ER and the AP (e.g., Wireshark running on the host that runs
wpa_supplicant).

In theory, this is not a required step if you are loading the AP
settings into the ER in some other ways. Though, in practice you will
most likely want to run wps_er_learn with the AP PIN prior to running
wps_er_pin (i.e., wps_er_start, wps_er_learn, wps_er_pin).
