Probléme san andreas mod installer

Bonjour,
qand j'essaye d'installer des nouvelles ou certaine voiture sa me fait : "this mod is not compatible with SAMI, therefore it can not installed .

NOTE: if it's a vehicle mod then it must have the required DFF and TXD files and they must be named correctly according to one of the game's vehicle (i.e banshee.dff, banhee.txd). Or if it's a mod other than a vehicle then it needs to have a script file created for it befor it can be installed with SAMI

svp aidez moi
merci d'avance
