Max payne 2 mod problem

Ok so i got Max Payne 2 finished it twice now i found this mod called Absent Grave.

It looks great i installed it started it but when i start a game it loads then it crashes saying sumthin like this:

A reference to shader''face'' in file ''Leanzombie.txt'' was made.

Something like that and it annoys me if anyone could help please help.

Thanks in advance
