I found a solution:

go to: https://myaccount.google.com/
admit access for lesser security apps

I have the same problem.
using Mac OS X.10,
google-sites-liberation-1.0.4
Problem/Error msg: "Invalid user credentials"
not using 2 stpes sign in 

I created a procedure for ISO 9001 purpose so, I am definitely sure that I am 
running accordingly. 
My last run happen on 2015.03.19.
But one thing I noticed, and it might/not be related to, is that after google 
set my account to "google apps" the liberation stop working.

I found another solution from google: https://www.google.com/settings/takeout
It run Drive Backup explendid, but not the site. I have two ones.

I am still without a backup solution.
