Help, i have downloaded and installed First Response and ELS but everytime i get in the game, it crashes. i watched video tutorials on how to install and i dont know why it keeps crashing. 

Did you install ELS properly? Make sure you drag EVERY  file in the "Installation" subfolder into your GTA IV directory. When asked to over right files, answer positively. Also, when installing LCPDFR did you check/uncheck anything when prompted to select which files to download? Make sure you only have 1 modloader. Do you have a cracked copy or the full copy of GTA IV, cracked versions are not supported. Lastly did you check if your game worked before downloading the files? And did you install the files on a clean install - or did you have other mods installed?

Try removing ELS or LCPDFR too see which the problem is. For the best support result, I suggest that you provide some more details :)

i got the full version from steam, i played the backup version without any mods and it seems to work perfectly fine. i didnt uncheck anything, i left the one box empty like it recommended. ill try to uninstall everything and reinstall. ill keep you  posted. thanks so far for the help!

Go to your GTA IV directory and open ELS.ini configuration

Go to the bottom

Turn these off:

Ai_Els_Sp = on

Ai_Els_Mp = on

See if game has stopped crashing.

yea the game still is crashing with the rc20 error. 

Any car mods installed? Try re-installing. @OfficerKauther

What Sergiyj said. Try reinstalling LCPDFR. If no luck. Try reinstalling GTA IV. Then start with LCPDFR. See if it works. Then try ELS.
