You wouldn't happen to being running Braveheart's Policing Script would you? If so, you just have to keep hitting E while aiming at them until it eventually works.

"I don't have to be careful, I've got a gun!"

I have it, and as far as I'm aware it's a custom font which you're not going to find easily on the internet. I have seen some high quality decal sets laying around though, so if you can find one of them you should be set.

Links or it didn't happen.

I'll admit it PPM was fun when it first came out. I had a blast responding to the high incident calls and being absolutely pelted with bullets when I arrived on scene but it does get obnoxious after a while. If you're looking for a action film every-time you play, I'd go with PPM. However if you're looking for a more realistic approach to a police mod which still has the action go for LCPD:FR. I haven't used PPM since 2010 so I'm sure it's changed a lot since then, in all honesty I'd try both mods out and see which one you like the best.

I wouldn't exactly call them negative comments, people have a right to express their opinion towards ones work if they like or don't like a certain aspect of it. Most people on the site just want to give you advise, not to bash you. You'll always get people like that, there's nothing you can do.

Well it says "2013 Ford Police Interceptor brought to you by Emergency Vehicle Installations (EVI)" down the bottom however I don't know of a 2013 model by him. I don't think it's Cj24's model though since I've used that and I'm pretty sure it has a different template.

EVI's 2013 Ford Taurus.

I call them Cruisers inside GTA: "122, I just 10-50'd. My cruiser's down." Though in real life I call them cop cars... because I'm lazy.

I'm not entirely sure since I've never gotten this problem myself so I'm just going off what I know (which isn't much). You said it was working fine before, did you happen to install any new mods?

If you can move and stuff then it has nothing to with your keyboard, it's more then likely an Dsound or Scripthook problem. You didn't happen to accidently delete your Scripthook or Dsound files did you?

I've had the SparkIV problem before but not the OpenIV one. As mentioned, check and make sure the GTA folder isn't set to read-only and if it still doesn't work try extracting the SparkIV files to the GTA IV directory and running it from there. As for the OpenIV error, I'm not too sure so try re-downloading it.

Emergency Lighting System Version 7 introduced a new "staging" system where you have to be in stage 3 to activate the siren. Simply press "J" three times until all the cars lights are on, then press "H" to turn on the siren, you can now switch between the tones by pressing "T".
