I have a problem
when I lunch the mod in the game it comes out an error that says "Error loading fastfile 'es_core_mod': Fastfile archive checksum (0xB425573A 0x40603FE2 0x49F6F169 0xBBE38E92) does not match executable nor any permissible"
I have changed the game language and says the same but instead of "es_core_mod" , says "es_core_mod"
anyone can help me?

NOTE: I didnt buy the game on steam so i cant verify the files.
