When I start GTA: IV and try to start LCPDFR by using ALT + P I does not start but when i install scripts my scripts work, My trainer and everything else works but LCPDFR will not start. I have tried re installing LCPDFR using the manual install. I have a dual Core 3.6 GHZ processor with a EVGA Geforce GTX 660, with 8gb ram, 430 PS. The scripts that I have in are policing, ALPR + Radar, K9 script. When I tried to start LCPDFR the frst time i didn't have any scripts in. and trainer did not work at first but installed LCPDFR the manual way then the trainer worked.
