This is my first post, and i'm technically unsure what part of the "Support" section i'm looking for. Recently, i wanted to replace the standard LCPD vehicles, so i watched Jeff Favignano's tutorial, i quietly followed through with the tutorial, and downloaded two vehicles for the police cruisers, but what confused me is that his video contained folders, mine contained WinRAR files, along with the cruisers i downloaded, these were WinRAR too. So i thought to myself "Uninstall WinRAR = Being able to import the files" Nope, because then i couldn't open the files as it asked me how would i like to open the file. So i reinstalled, but i made the dumbest mistake as classifying them as "wrar_en.32_.exe" making my files unimportable. Now i can't import them, so how do i fix it? i've changed it to the WinRAR archiver, but its still not fixing my problem. Edit: I've actually made it worse, now no AI vehicles can spawn, and if i try to spawn a vehicle via the Native Trainer, the trainer freezes on me.
