Can't branch projects on Launchpad

I have been using Bazaar successfully on Windows 7 for a bit over a
year.  When I try to branch a project on Launchpad, I get output like


2012-01-25 11:17:43.20 D:\Develop\bzrhooks>bzr branch

You have not informed bzr of your Launchpad ID, and you must do this to

write to Launchpad or access private data.  See "bzr help

This used to work.  It is, for example, how I installed the bookmarks
plugin when I set up Bazaar in the first place.


I think it has to do, somehow, with something I did last week.  I
already had Bazaar installed from the Windows installer ... I believe
2.2.1.  Last week though I wanted to do a trial conversion of one of my
branches to mercurial using their convert plugin, and I needed to be
using the Python version of Bazaar in order to do that.  So, without
uninstalling the Windows build of Bazaar I already had installed, I
installed Python, pywin32, and Python edition of Bazaar (as well as the
Python version of mercurial, although I don't think that's relevant
here).  In fact I installed and uninstalled all of these things several
times because I don't really understand the Python ecosystem and I had
mismatches between the Python version and these other programs, as well
as bitness (32 vs 64) issues.


I didn't ever get my convert working and I decided to try again on one
of my *nix systems later.  I uninstalled everything ... all Python and
everything that depended on Python.  I left my Windows Bazaar install
intact though and it does work for most operations.  When I tried
branching some plugins from Launchpad this week though I got the error
above.  So I uninstalled Bazaar and installed the newest Bazaar (Windows
build), and it didn't work.  I deleted my %APPDATA%\bazaar directory
thinking there might be a conflict with something I had in there, but it
still didn't work.


Other developers here can successfully branch from Launchpad so there is
definitely something messed up with my system.  I just don't know what.
I would appreciate any assistance you can offer.  Or if this is the
wrong forum, just let me know where to go.
