Problems with existing pytivo install and my new Premier Elite

My S3 died on me earlier this week and I decided to replace it with a Premier Elite. Got everything up and running last night and found that while I could pull down video from my PC through the directory that the Tivo Desktop uses, I couldn't pull anything down from the directory that pytivo uses.

If I try to download something on the Elite from the pytivo list of videos, it looks like it should work - ie. the Tivo tells me that it is scheduled, but nothing ever happens. I've tried stopping and restarting pytivo. I have not rebooted the Elite.

If I log in to the pytivo interface on the PC and try to push a program to the Elite I get:

No option 'tivo_username' in section: 'Server'

Traceback (most recent call last):
File "C:\Program Files\pyTivo\plugins\video\video.py", line 484, in Push
m = mind.getMind()
File "C:\Program Files\pyTivo\mind.py", line 259, in getMind
username = config.getTivoUsername()
File "C:\Program Files\pyTivo\config.py", line 39, in getTivoUsername
return config.get('Server', 'tivo_username')
File "C:\Python26\lib\ConfigParser.py", line 540, in get
raise NoOptionError(option, section)
NoOptionError: No option 'tivo_username' in section: 'Server'

if I look in my pytivo.conf file there is no "tivo_username" option in the Server section. There is logging information about the request in the debug.log but no actual error messages to tell me more about what the problem may be.

According to the entries in my Start/pytivo list, the version looks to be wgw-2008.10.15.RC1.

Have things changed in the Elite so that things need to be tweaked in pytivo?

The Elite is running 14.9.2-01-2-758

Thanks for any ideas.
