Hi everyone,

 

I am getting a "Failed zlib call" error.  I have tried verifying my game files, but this has not worked.  I have also deleted all unused mod vehicles from my DLC Packs folder.  I have also removed all non-vanilla lines from the DLCList, as well as all ELS files that were for old DLC cars.  

 

I am not sure why I am getting this error. Does anyone know why this might be happening?

Rename mods to _mods and test after each removal.

Hi @UnknownBastion . Even after renaming my mods folder to _mods the error still occurs. Any other ideas?

Keep the folder named to _mods. Then remove ScriptHookV.dll and test.

Hi, getting rid of Scipthookv.dll and changing the name of my mods folder to "_mods" worked, but now my "Replace" cars are gone. Any other suggestions.

Removing, then replacing my Scripthookv.dll seems to have fixed the problem.

Hmm, the problem is back. This time removing and readding Scripthookv.dll hasn't worked. Any other ideas?

Rename _mods back to mods and keep ScriptHookV.dll removed. See if the error persists.

Hi,

I tried to do a clean install of LSPDFR, and although my game is up to date, Rage Plugin Hook is stating that RPH is out of date. I used the RPH that was included with the LPSDFR install files.

Can you screenshot that error message?

Hi,

It looks like the same error you get when the game has updated and RPH needs an update, however I just downloaded LSPDFR yesterday, and I don't know why the RPH file in the download is not current. It normally is.

According to the download log, the RPH application was last modified on 1/28/26.
