I've been playing this game for quite awhile, and hadn't had an issue until upgrading to 1.1 (previously had 1.0d).

I would go down the list and post my system specs, but I can assure you, my system is MORE than capable of handling this game.
I've mostly played using Windows 8.1, but now have ran it with Windows 7 compatibility. STILL I have the crashes when I arrive on scene to the following callouts: (LCPDFR callouts & Callouts+ 7.0.1 installed). 

-Disturbance from Homeless
-Shots fired in xxxxLOCATION
-Vehicle fitted with a tracker
-Suspicious Activity (doesn't crash, but will permanently have the yellow circle, even after I quit LCPDFR mode)

I've also tried removing and re-installing LCPDFR, and the results yield the same.  Thank you in advance for any help.

 

Shots fired is broken with Callouts+, which supplies the Tracker callout.
Try removing all your API scripts.

Ah, I knew the "Officer Down" one was broken, I didn't realize the "Shots Fired" one was too. What do you mean by API scripts?  Additional mods or scripts that I downloaded?

Things like Callouts+

Ah Gotchya!  I apologize, I have ZERO programming skills. My expertise is mostly hardware based and such.  I've built rigs for several people many times, but as far as programming, I've got nothing.  I leave that to all the awesome people who upload here! :-)  Thank you for your help.

So I did what you said; I removed Callouts+ and sure enough I can finally do my homeless callouts again.

Are there any other additional callout scripts that you know of that is more stable?  (I do miss the easy medic and car removal service of callouts+ though; I found vDH to only work the first time for me, but after that the vDH scripts would stop running).  But thank you, lcpdUnit22, your solution has worked for this topic! :-)
