Hi John,

Hmmm... a few things to check:

Do you have a file 'usno_b1.tdf' in your Guide folder? (It's supplied with the Guide
update file. If it's not there, something went wrong with unZIPping guide8.zip.)

In "Toggle User-Added Datasets", it should appear under "USNO B1.0 from hard drive".
(Just checked, and this should show up even if the B1_PATH variable isn't set.)

The c:\b1 folder ought to contain 180 numbered sub-folders. There should be a
file c:\b1\179\b1790.cat that is 591840 bytes long. The entire dataset should be
about 80 GBytes. I mention this because I gather there are some B1.0 subsets and
re-formatted B1.0s floating around out there. A subset will probably work (and you'll
see the b1799.cat file; it'll just be smaller). If the dataset is re-formatted,
Guide won't understand or display it.
