Please update your bot first. Current release is r9843 and we couldn't examine that old stuff. As login.py worked as well, API is on. Please again create a new family file with the new release and try the command login.py -test This should determine whether the not is still logged in. If this does nothing, try login.py -test -v which prints additional I formations and give us the results and the new results of version.py too.
