I had started a new save each time. Just doesn't seem to work for me.I didn't even know there was an experience cheat. You might have to start over or load an earlier save
Idolninja i didnt find the files .\steam\SteamApps\common\Saints Row IV\
Which application do you use? I'd recommend WinRar, it always works in my case.This mod doesn't work, i can't even extract it..
In fact you can use free version of WinRar even after the trial period. After 40 days it only reminds you about buying a license each time you start it but except that it still works as usual.7-zip is free, which is why I tend to recommend it over WinRAR, but they can both handle it.
Or you could have just searched for info. http://lmgtfy.com/?q=rar file
If you mean it's corrupt, download it again.
