Yeah, you definitely need to update your game then. Most newer mods, like LCPD:FR, only work on 220.127.116.11, whereas PPM works on some of the older versions. From my experience, the best version is 18.104.22.168, which is also the best one for adding vehicle mods and graphics mods. After that patch, Rockstar Games decided to dump the good shading/lighting system and replaced them with terrible, crappy, poorly-programed BS ones. Not only does this cause the game to look like "ilovepoop," as some users have called it, but it also lags the game A LOT, not to mention crashes it more often too. With 22.214.171.124, I am able to play at constant 60 FPS and no issues; everything looks great. With 126.96.36.199, everything looks like crap, and the FPS drops to 40 all the time.
So it ultimately depends on what you want to do. If you want to play the latest version of LCPD:FR, you will need to patch to version 188.8.131.52. If you don't care what version of LCPD:FR you play, just so long as you can be a police officer (like me), then go for 184.108.40.206. It is simply the best patch.
