Did you change it from reg_XYZ to login_XYZ, and that fixed the issue?
Please report this bug if you haven't already (this is just the support section). That's a pretty silly and quite annoying bug, and means that arbitrary users can end up being caught in infinite loops just because of choice of ID value. :/
