Siren mastery issues and wilderness plugin issues

Hi love that u can post help here and hope i'm posting in the right spot sorry if im not

Few questions I,m new to this and not a big computer friendly person. So i need some advice, hopefully u can help.

So i followed your install advice custom sirens into plugins/siren mastery and sirensetup xml and replace the one in the siren mastery folder. So wat do i do now! I have started GTA5 but i still have the old sirens how do i get the sirens i just installed. Any help will be greatful.

The siren pack was made by 72will

is there anything else i must do, I am hopeless at this sort of stuff but love this modding shit 10/10

2nd question is! I have install wilderness plugin followed the directions which was easy but the game crashes after loading the main plugins, so when i remove wilderness plugins the game works fine how do i get the wilderness plugin too work i want the callouts they look awesome??????
