I am going to confirm that ELS is absolutely broken. Instead of making 1,000 other threads. Brand new GtaV install, no mods installed except LSPDFR and ELS (and some ELS compatible police cars) at the moment, I will also do the suggested and delete OPENIV.asi and reinstall it, Ill post back
Deleted OPENIV.asi in GtaV directory, Opened up OpenIV, Tools, ASI Manager, OpenIV.ASI Install, Double clicked RAGEPluginHook, that auto started R* Launcher, ELS failed to initiate.
Pressing <- on the controller or [J] did not activate lights or siren. It is broken.
Ctrl P usually brings up ELS Console, nothing at all.
