It is set to enable.
I mentioned that it was ticked properly in the config file in my very first post.
Honestly that was one of the very first things I checked, just to be certain.
Sadly the answer to my problem isn't quite so simple.

So far nothing I've done has stopped it. I tried running with only awesomemod, so I'm fairly convinced it's not tightpants but simply my install being a dick. It's been giving me attitude since I installed Diesel.
I also pared down my CC, just in case it was simply too clogged to work properly. It's amazing how much 5gigs of crap can clog up Sims.
I have a temporary "fix" by installing the nraas NoDisc mod in conjunction with awesomemod. I can now launch from .exe with no DiscCheck.
Oddly enough, the nraas NoDisc alone doesn't work either, so that is nifty. Tried that just for shits and giggles.
I'm hoping that once Supernatural comes out I can installed it, patch, and download a patch-compatible awesomemod and it'll go away and leave me be, but until then this seems to be working.
 Thanks for replying though, it's good to know it isn't affecting other gamers. Means the issue is somewhere in my game where I can fix it.

Edit: Got rid of extra quotes.

I've tried them all, actually. From Launcher, from .exe, and I even did the insane and reinstalled origin to attempt to launch from it sans-disc.
If it's working for you and you're freshly patched then I probably just borked my game somehow. I already tried sans-cc, but I will try culling and see if that helps any.

I know someone a bit back mentioned the same thing, so we might have a related problem. I'll see if I can find the post and edit with the info.

ETA: I found it! Page 30, by RebelRed.

After installing the Diesel SP and updating to the newest patch version, Awesomemod is no longer disabling the check for disc feature embedded in the game. Completely updated version of AM with a brand new config. Also, before you ask; yes, the option is ticked properly in the config file. I double checked that just to be sure.
Also, it isn't a case of tight pants. I moved all my mods to my desktop and tried with only Awesomemod and the config file in my mods directory (and the resource.cfg of course.) Still doesn't work.

I have legit installs of basegame and all EP/SP. Mine are all registered with Origin, and even the 'Launch from Origin' option won't allow me to launch sans-disc. My patch level is 1.36.45.017017
If it matters at all, I have all the arr'd store content, properly decrapped and installed via Launcher.

Have anyone else has any problems at all regarding the disc-check? I'm aware I could just put the disc in, or mount it on a digital drive but that seems quite the hassle when Awesomemod is supposed to disable the disc-check anyway.

ETA: Just had a brilliant flash and decided to check my resource.cfg, in case it might be the culprit (I had downloaded a fresh one, just to be on the safe side.) Turns out that it was useless; however I have since fixed my resource.cfg and I still cannot get the disc-check to stop. Just thought I'd heads up; it's not the resource.cfg file.
