Hello.

The freval error was fixed for some users by doing this: Open up your LCPDFR.ini, look under "Main", it should look something like this by default:

[Main]
AdditionalCopCarModels= 
SuspectTransporterModels=POLICE;POLICE2;PSTOCKADE; 
VehicleTrunkWeapons=Shotgun_Baretta; 
AllTextMode=False 
AmbientScenariosMaximum=2 
AmbientScenariosMultiplier=250 
DepartmentName=Liberty City Police Department
DepartmentShortName=LCPD
FirstStart=True
UsingPoliceStationMod=False

Now, add to the bottom of that part

PreloadAllModels=True

The "Main" part should now look like this:

[Main]
AdditionalCopCarModels= 
SuspectTransporterModels=POLICE;POLICE2;PSTOCKADE; 
VehicleTrunkWeapons=Shotgun_Baretta; 
AllTextMode=False 
AmbientScenariosMaximum=2 
AmbientScenariosMultiplier=250 
DepartmentName=Liberty City Police Department
DepartmentShortName=LCPD
FirstStart=True
UsingPoliceStationMod=False
PreloadAllModels=True

so, i tryed your thing, it didnt worked..... also i reinstalled it again...

 

Are you running the game as administrator? Legal copy of the game? 

yep, game bought from steam, but as i said before, it worked before i played online, after online gameplay it has a CTD without warning or error...

Have you made any changes to your system? Installed mods? Did you save while on duty? 

i didnt saved wen on duty, and added no mods..

Try to manuall install the mod '?do=embed' frameborder='0' data-embedContent>> Also make sure to run both executables as administrator. 

i was trying that now, will tell in a bit if it works!!

Okay good luck :) 

so tryed that, now getting error after pressing play...   SecuLauncher:    failed to start aplication. [2000]

Download, run and install this: http://www.microsoft.com/en-us/download/details.aspx?id=5549

well, i canda fixed it myzelf, tryed to start via steam: error
run without steam (run as admin, launch gta) worked!!!!

Thanks for the help!!
you are the best!!!!!!!!!!!!!!!         

Glad it got solved, happy gaming! :)
