I have tried reading the troubleshooting page on this situation, but it is difficult to follow and doesn't go into much detail. This is the first time it has happened and it tells me that the file I am missing is "gmp_tal_crystal_skull_perfect_01_a_di". I haven't played the game for months and I didn't have this problem before. I really want to get back into the game but I cant seem to find a way to fix this.
P.S. I have tried uninstalling and reinstalling multiple times
