Aeon Nox (GIT) uninstalled itself

I had this strange issue today I open up XBMC and then Aeon Nox (GIT) updated like always. This time XBMC went black so I had to do a force shutdown. When I restarted XBMC was back at the default skin.

I tried to re-install Aeon Nox GIT but get install failed. So I shut down XBMC and check both folders user data and program files and there is no svn version. I still have Aeon Nox so I have no idea what happen to the GIT version or how it unistalled itself from my computer.

Any ideas how to get it back?.
