My problem has been fixed. I just did an automatic install on the "mods" folder and It worked 10/10
So if anyone happens to have the same problem just reinstall in the "mods" folder with OpenIV, seems like the DVD or Rockstar Warehouse version of the game tends to replace the files that had been changed by the original ones. (So, if you edit an .RPF file, the game will download the original one and replace it, so you have done nothing)
This explains it better than I do: http://openiv.com/?p=1132
Thanks for the support.
PS: I love this.
Patchday9ng is the most recent I have, did it manual and stills update after I launch and nothing new. The Files that I put in "x64e/models/cdimages/pedprops.rpf/" dissapear after the update. The ones in Patchday9ng still remains.
