Armored Core 4 [BLUS30027]

Hmmm sure, I don't know how to write that up yet on github. It seems like it's a local problem so far though, since even on AC:fA, other people can launch fine with R/WCB turned on, but on my end it immediately also said 'access violation writing location error' after the first loading screen, right before it actually gets to the in-game tutorial.

I'm thinking it might be some sort of weird permission thing going on? I've tried launching as Administrator but it didn't help either.
