I recently asked this question about how to encrypt software on my machine. One of the answers suggested Cryptkeeper, so I installed it from Ubuntu software centre. The installation proceeded without reporting any errors, but I am unable to use the software. I access it from my System Tools menu and absoultely nothing happens. Has anyone else experienced this problem? Is the best solution to uninstall and reinstall or is there something I am missing in how to use it (although I don't see how) ?? I have never experienced any problem like this before with installed software - it always 'just works'.
