I have installed ELS and but it wont work, when i press 'J' or any other ELS key it does't do anything at all. The only way I can make the lights go on is pressing "E", wich only activates the siren sound as it would do in the normal version of the game.
I have tried: reinstalling ELS, installing another version of Advanced Hook, unistalling and installing ASI loader and Open IV.asi, reinstalling the vehicle pack but any of this works.
