You should really cut and paste the *exact* command and error message,
we can't tell much from this. Don't worry about spamming us with too
To return to Cabal-1.0, you should simply unregister Cabal-1.1.1,
assuming you haven't also unregistered Cabal-1.0.
'ghc-pkg list' will tell you which packages are registered, and whether
they are registered globally or locally to you. 'ghc-pkg unregister
Cabal-1.1.1' will unregister Cabal-1.1.1, for example. If it is
registered for you only, then you will need to add the --user flag.
Additionally, you probably want to delete the files that belong to
Cabal-1.1.1. 'ghc-pkg describe Cabal-1.1.1' will tell you where the
files live (before you unregister it, of course).
