Gonna need more info then that.
Have you tried Alt+P to activate LCPDFR?
 
Thank you for asking the LCPDFR community for help. We do the best we can in solving all and any problems. Some helpful things to keep in mind while posting:

    Make sure you aren't using a crack - We don't support cracks
    Update GTA IV to 1.0.7.0 (the latest version of the game, or 1.1.2.0 for EFLC) - This sometimes fixes a wide variety of issues
    Make sure that you run the game as an administrator.
    Make sure that your GTA IV root folder (and every subdirectory) is not set to "read-only"
    Ensure that ScriptHook.dll, ScriptHookDotNet.asi and Dsound.dll OR Xlive.dll are in the GTA IV ROOT folder
    Ensure that there is a folder titled 'LCPDFR' in the ROOT GTA IV folder.
    Check that all the above files exist, if they do not, reinstall LCPDFR with the MANUAL installation.
    Ensure that you are using up to date versions of every LCPDFR dependency and LCPDFR itself.
    
Make sure these are installed and up to date:
