I had the same problem a few days ago. I ended up reinsatalling the whole game, after countless hours of trying to fix ELS. Now it works just fine.
If the thing bob mentioned isnt working, try something that once helped me:
- download the latest version of scripthook
- remove the old one from your game folder
- remove the whole ELS folder from your game folder
- open OpenIV, uninstall ASI loader, close OpenIV, Reopen OpenIV and install the ASI loader
- restart PC
- install the newest scripthook
- move the ELS folder back into the game folder
hope it helps
