Can't launch Nautilus

I just upgraded my Unity to 5.0 , but it wasn't very stable, so I downgraded it using purge. But after recovering, I found that nautilus doesn't work. I tried to open it on terminal and got this:

nautilus: error while loading shared libraries: libnautilus-extension.so.1: cannot open shared object file: No such file or directory

I reinstalled it, but it didn't seem to work.

I just installed Marlin file browser, from the marlin-dev ppa.

Problem is, wehn i try to launch it, i get this error:

stewart@StudioLaptop2:~$ marlin marlin: error while loading shared libraries: libunity.so.6: cannot open shared object file: No such file or directory

What should I do?

P.S. - I've tried it in Gnome-shell and Unity, but get same error :(

Thanks,

Stewart

I upgraded the system, using instructions from file UPGRADE.txt on the disk. Everything works fine. But when I try to startx, it quits with an error:

ck-launch-session: error while loading shared libraries: libffi.so.5: cannot open shared object file: no such file or directory

In /usr/lib I found a file libffi.so.6.
