I've already done all of this, too. I also did all of this back in beta.
Did a clean boot. Reformatted my hard drive. No dice.
I've done what you recommended with the SWBFII folder in \Documents\. No dice.
Origin and SWBFII are whitelisted in my firewalls and AV. Running the game with both of those flat-out disabled doesn't work, either.
I would open chat support then, and link this page to them and tell them you did all this already.
When you did the reinstall, was the reinstall from the trial version? If so, it is missing files and they suggest redownload from the actual preload/download now.
I added a couple things to the post above.

Somebody else that had this problem did steps in a specific order and was able to get the game to work, and hadn't been able to previously, the post is linked below,
