"GTA IV Has Stopped Working" after a while. Most likely LCPDFR

I've been getting this ever since I (manually) installed LCPDFR 1.0d

Fairly sure it's LCPDFR, since I can play for hours and hours upon end with nothing going wrong without the mod active, but when I'm in my uniform, the game feels the need to crash after 10 or 15 minutes.

The mod itself is working fine so far, no errors or whatsoever. Instead, the whole game just crashes.

Yes, my PC is capable of running it, no I don't use vehicle mods not anymore at least, seeing as they just caused problems.

I do have a few other mods, but I doubt they would cause issues, seeing as a lot of people use them without any problems.

I play with the following mods:

CryENB (High-end setting + my own tweaks)

HD Street and sidewalk textures

Simple Native Trainer

Simple Fuel Script

PoliceHelper (with all world events turned off)

Trafficflow V5 R2

My LCPDFR and Scripthook logs give no errors, just the same old warnings about audio files and something about a custom content manager regarding pedestrians.

I can safely say that this is starting to piss me off. With 1.0c it was the script crashing and giving errors, now it's the entire game crashing. But only when LCPDFR is active!

What can I do? Am I overlooking something?
