Try cleaning and rebuilding your prog, you've probably got existing .hi
files that refer to the older package version. That or perhaps you are
using other packages that were built against Cabal-1.1.6, eg the ghc api
package. You can force ghc to use a specific version using "ghc -package
Cabal-1.1.7" and see what it complains about.

You can re-register the old version, though I'm not sure where you can
get the right package.conf file from. If you built from source you can
grab the file from the build tree. If you installed from a distro
package then re-installing that should be easy.

Ask on the cabal-devel list, I'm not sure without delving into the code.
