*Sigh* Looking at the Emptool sources, 0x80040057 is UPG_E_SOMETHINGBAD, the associated error message being "Something bad happened".

Upgrader::ErasePage() has failed for some reason, but the exact error code (which would have allowed us to determine whether you have a connection problem, or a player problem) is thrown away and replaced by meaningless generic ones twice before being reported to the user.
