You're signing in through your facebook information correct? If not, go ahead and sign - up through LCPDFR(if you haven't, you didn't really specify) with your Facebook information. Officer Jim.

Alright, reinstall GTA IV, (with a FRESH GTA IV INSTALL!) slap the 1.0.7.0 US update on there, then slap JUST LCPDFR 0.95 RC2 to it. If you can play 5+ minutes without crashing, install ELS V7, once again, play 5+ minutes, no crash, install ONE CAR MOD AT A TIME. LCPDFR WILL NOT WORK WITH TORRENTS/CRACKS! Oh, and here's something that you should know before trying to install car mods -> ALWAYS BACK UP THE ORIGINALS BEFORE MODDING!!!! If you could please try that, then PM me. Maybe we can get this problem for you resolved. :) Officer Tim.

Change the keybinds in "ELS.ini" Which can be found in: C:Program Files (x86)Rockstar GamesGrand Theft Auto IV(this is called the root folder) Or C:Program FilesRockstar GamesGrand Theft Auto IV Mines the top because I use a 64-bit computer. Change the keybinds as needed. <- Edit -> Make sure none of your other mods interfere with your ALT + J keybind, sometimes having Alt+Tilde(which is "~" which is the button besides "1" on the American/US keyboard) doesn't interfere with anything. If sometimes, can also be a bug/glitch. Have you restarted the game and tried to turn your lights on and off? Officer Tim

Okay, this happened to me, if you have IV Dash Cam, TAKE IT OFF. I went from 15 fps to running 40. For some reason, my computer lagged because of IVDashcam. If you have it installed, I'd try that.

Could you tell me your specs, and what script you're using?
