Today I started to analyze with fritz games at lichess (but I have not played till the April 21, 2013). I saw that after that my results (Elo 1520, played 2011-2013) annulled and an inscription "This player uses chess computer assistantse." Look at my games, they have a lot of errors, program would not do http://en.lichess.org/analyse/hv4qg3qv/black
