A. I do beleive this is an issue check these
Please do the following:
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. Install these: .Net Framework 4.5, Microsoft Visual C++ Redist 2012 B. This doesnt make since since the Trainer was started are you able to us this at all. I wonder... have you installed LCPDFR then the trainer? I would try installing the trainer disabling the keys and then install LCPDFR I know it uses the mos recent scripthooks, advancehook etc

Alright here you go

1) they coded the busy function backwards, no puns just trying to help, so turn it to busy as in not to recieve callouts, that is what I have been doing till they get a chance to look at the other issues.
2) Havent had that problem are you pressing ALT E when the run to call it in or are you getting that option I miss the opition and do the same thing your doing.
3) Happened at first but I stand far enough away from them and oddly they turn around for you to frisk or arrest instead of having to get behind them like in R2
I am in no way a coder or know alot of stuff these are just my observations and I hope they help you
