This is a problem with the CFMX 6.1 uninstall. It doesn't know that the
CFIDE in your web root isn't its own, so it goes ahead and removes it. This
is a problem when you migrate then remove 6.1.

The work around is to reinstall or better yet, make a copy of the CFIDE
directory before you uninstall 6.1, then copy it back again.

Sorry about that, but since the problem lies in the *old* installer, we
can't really fix it. :-(
