well everything is in the S4 Folder, I start and log in etc and i head to the lobby with the current clothing / weps i want.
i Run as admin for the injector. i find the .DLL & i click inject. and nothing comes up?
maybe you could try to delete all the things in the s4 league folder and make sure you also delete the fmod.dll too with the others and then try to redownload the folder and readd it in it worked for me when it didn't work for me once
Edit: Only delete the things that were in the IDchanger folder and also the fmod.dll.
do you have all the files from idchanger folder in your s4 league folder and run the injector as admin? and inject the IDchanger.dll into the injector?
