If after first time you start MAZAIKA you can't do anything
Please try again and be shure that:

You index at least 500 pictures 
(you can see it in Picture base -> Main info "Cell database file"

You pressed <Repaire> button at least once after base
was created. (It's no bad to press it again - and it's very bad
not to press it at all)

At least one "Tile radioboxes" is enabled
At least one of enabled "Tile radioboxes" is cheked

Don't use too much number of tile (at first time)
15 - 25 is enough for a first time (just to see that program works)
