Thanks!
I already tried hitting install last week ... and it did not work, but ...
I tried it again today and so far it appears to have solved the issue as I am about 45 minutes in without getting that message.
I'm not sure what I did differently this time (or last time - perhaps I flashed clockwork first or something - I know I did a ROMMan backup before).
For anyone who does try it, it will look like it is upgrading and the status bar will go 1/4 of the way and then the Android with a big ! will appear. Don't panic - just hit the power button and the clockwork recovery will appear with the option to reboot.
