I got this when I try to install:
Finding update package...
Opening update package...
Installing update package...
Amend scripting (update-script) is no longer supported.
Amend scripting was deprecated by Google in Android 1.5.
It was necessary to remove it when upgrading to the ClockworkMod 3.0 Gingerbread based recovery.
Please switch to Edify scripting (updater-script and update-binary) to create working update zip packages.
