EUP and LSPDFR won't work

Its been 2 weeks since I started having this problem, some months ago I uninstalled my gta5 for some reason which I forgot, its not important tho, now, for the past 2 weeks I've beet trying multiple things and searched a lot of videos and forums and either I couldn't find what I needed or there is not fix yet (idk), I said to myself I could fix it quickly but apparently I am getting more and more frustrated. First of all I have installed LSPDFR with the usual Stop The Ped , Ultimate backup and some callouts, the same callouts I used before and worked perfectly , then the EUP which also I used previously and worked perfectly, now after I reinstalled all these again its stopped working properly for some reason, I can't go on duty because the Mission Row police station door is locked and if I try to enter in the room I get 3 stars, I tried to Airbreak my way in with a trainer and the blue circle to go on duty was there, when I pressed E and the "go on duty" LSPDFR crashes, besides that EUP doesn't work either, the uniforms are all messed up, with missing body parts and wired cosmetics all around... I can't even open the EUP menu even is the plugin is present and LSPDFR configurator recognizes it as a active plugin... 

I have recorded a little of this: https://www.youtube.com/watch?v=0QqLiQ7CThM

If someone could help I'd be forever grateful
