Yesterday my Gta worked fine. I have LSPDFR, rage, eup, sup, several plugins, and several vehicle mods installed. The thing is though yesterday I did not change, modify, download, or install anything. This morning I tried to load up gta with LSPDFR and got the error "err_fil_pack_3" which says corrupt game data, please reboot, verify the game data, or reinstall the game. I tried without lspdfr and same thing. I have narrowed it down though to any add-on packs. I found out it works fine and loads up without addon packs but the moment i try to put just one addon pack, it does it for any pack I have, it pops up with that error. Any help would be appreciated. Thanks 

Its most likely your mods folder. what dlc's are you using?

Things you can try:
1. Install the Gameconfig, Heap Adjuster, and Packfile Adjuster.
2. If that doesnt work, remove what you have added recently and test after each removal.
3. if all that doesnt work, restart your mods folder.

I have gameconfig, heap adjuster, and packfile and have tried to "filter" the mods to see which one may be causing the problem but any addon doesn't work with the game. I take just my eup file and add the writing in dlclist, i get that error. I choose a random carpack and do the same thing, boom error. I really don't know and my only option is to reinstall, but I'd lose all my mods so I would like to not do that. I have also restarted my mods folder by delating the old one and replacing it with the fresh update folder, which works fine till I put one addon file in the dlclist.

Thank you both for your help but I found my problem, unfortunately. It turns out that overnight, all of my installed addons became corrupted, If you could know how this happened please tell me, which means I need to redownload these mods and re-add them. The weird thing is none of the mods seemed corrupted in Open IV and looked perfect. Still, I have no clue how this happened but found out by downloading a new addon vehicle mod from LSPDFR and installing it. It worked fine somehow. Thanks again.

Guess what! Turns out it was just my game "time of the month". Reinstalled THE SAME mods folder and it works fine. Like nothing ever happened. I you encounter this problem just give your game some space, its favorite movie, and some chocolate and you'll be fine. It's a love hate relationship.
