Using many hint pieces closes the program immediately

If I put many hint pieces the program ends immediately.
I am trying with maybe 150 hints (from promising scores generated by eternmanshare or RMC best scores) or even from the grids I previously generated which are on the Statistiques page).

It seems v2.1 doesn't like hint files with more than a few hints (up to now I have been using the hints from clues 1 and 2).

Antoine: Do you know of a limit in the number of hints allowed?
