Oh boy, this is one those "geeky" things that the masses won't understand. How did you implement this solution, in layman's terms? This is happening to me as well.
The masses should learn to backup their wallet and the bitcoin folder itself. 7zip is free software (but please make a donation if you can, its good software )
