Alright it has been a while since I had played this game and recently re-installed it, had a lot of issues at first mind you but finally got it running without problems.
Since the last time I had played the game I had all of the mods which I had downloaded saved though some of them back then I hadn't used and would like to have now in-game.
The issue I am having is figuring out how to install multiple fire trucks into the game (I have a more vehicles mod installed which has policeb, police4 etc) and to my understanding I cannot use SparkIV to add in new files where I can with OpenIV however, when I try to drag and drop the files into OpenIV it gives me an error telling me that I cannot add new files.
So what I was wondering was, if anyone had any experience in adding and not replacing new vehicles with OpenIV?
How could I go about doing this?
Thanks
