F1 2014 1997 mod don't start anymore

F1 2014 The Game (Codemasters)
Hi guys,
I know maybe this would never be seen but I try...
I've always had two version of the game on my pc
2014 and 1997 modded

2 different folders, I name the one i want to play "F1 2014" and then start it from steam
always worked
always loved it

today I wanted to restart 1997 mod after I don't know maybe 6 months and it crashes without even starting (just a black screen for a while)... Original 2014 still works but the modded one no... has happened something? someone know if I can solve it?

it would mean a lot... thank you
