You are probably running into a known issue CM has with HypersonicSQL
(the embedded database Cayenne uses to save preferences -- an "eat
your own dogfood" kind of thing). Unfortunately, the simplest thing
to do is delete the preferences DB and start over. If you look in
your ~/.cayenne/prefs/1.2 directory, you'll probably see multiple DB
files instead of just one and somehow HSQL is using the wrong one. If
you are on a Mac and use Time Machine, it is possible to go back and
find a working DB and restore it, but still painful.
Cayenne 3.1 is scrapping HSQL, but that probably doesn't help you ...
