Q: I installed model and run the game but after some time of playing it is crashed. What is happened?

A: Such situation may happened when you replaced vehicle what was previously saved in game (parked on parking near flat).
Game can restore modded vehicle from save incorrectly what can do it unstable and it can crash.
If you have such situation you should definitely remove all modified vehicles from all parkings.
It can be quite difficuilt to remove vehicles from all parkings at once due to game instability and quite long distance between them.
It is recommended to save game and restart it after removing vehicles from each parking.
It increases the chances what game will alive longer and you can to arrive to next parking.
Unfortunately sometimes it does not help even if you remove all modified vehicles from all parkings. In such case you can try to start new game.
For models spawning use trainers like Simple Native Trainer.
It can spawn any vehicle (original and modified) and have many other interesting features.
Try to investigate their possibilities and remember what modding is only for fun, not for game walkthrough.

Q: Is there application version for PS3, XBox or Mac OS X game versions?

A: No. Application is designed and tested for standalone and Steam Windows game versions only.


Q: I installed several models and now in my game I see only taxies. Why?

A: It is well-known "Taxi Bug" issue in GTA IV engine. It starts to spawn the same vehicle when it can't to load models to memory.
Generally there is no solution for this issue, but there is workaround for it.
There are several modifications, like Traffic Flow which try to spawn random vehicles before game engine spawns taxies.
It can works but such modifications can spawn too many random vehicles what is "hard" to game and it may slow-down or even freezes.
