As of lately I have been able to play GTAIV rather well, being able to run it for about an hour to an hour and a half before having to restart due to memory issues. 

However, since last night and now today, the game crashes after about 10 or 15 minutes.

I'll enter the game, start LCPD:FR, go to the station and all of that, and when I start patrolling, or if I take a call, I freeze up while driving. I don't get an error message like when I run out of data, the game simply freezes, and then closes out entirely, taking me back to my desktop. I've tried reinstalling the entire game, and it still does the same thing. I ran the LCPD:FR Diagnostics tool, and it comes up with this message. http://prntscr.com/caih6d I also have attached the LCPDFR.log to this post.

also, if you have FinKone's Police Orders Mod installed, remove it.

Took care of it, it seems to have been the cruisers I had installed.
