Game Keeps Crashing. Please Help.

Hello.

I have been racking my brain to figure out what's causing my game crashes. I have studied the log file over and over, and it does have several warnings, but I'm not sure as to what they are referring. Let me add my log file here and see if anyone that's more experienced in modding GTA can give me some insight, maybe even a fix, if possible.

Before I do that, allow me to list some of the mods I have enabled.

1. LCPDFR

2. ELS v8

3. Policing Script

4. Bravehart ALPR

5. Callouts+

6. Police Helper

7. Simple Native Trainer

8. TowHelper

9; GTAPolicing Tools

My system specs are rather low, but I normally have little issues running GTA4. I've already beaten it before I installed LCPDFR and the mods mentioned above. Either way, here are my specs.

Mid 2009 MacBook Pro, Intel Core2 Duo at 2.8Ghz, 4GB RAM, nVidia GeForce 9600M GT video card, dual booted with MacOS X and Windows 7 Professional 64 bit.

It won't let me upload the log file, so I'll copy paste it below. Thanks for your time.
