So i'm getting the above error when I try and launch the game. I played the game without issue about 15-16hrs ago and haven't made any changes to my computer since.

I doubt it's actually a memory issue. I have a Ryzen 1700x running 32GB Corsair 3200mhz ram with a GTX EVGA 1070 graphics card.

Things i've tried:

I clicked the button to go online for a solution. It told me to check 2 URLS and make sure I could talk to the Easy Anti-Cheat servers, which I can cause I got the 200 - HTTP OK message.
I made sure I was running the latest Microsoft Visual C++ Redistributables and graphics card drivers.
I did a SFC /scannow. First pass did find 2 corrupted files, which it fixed.
I did a windows update, again I had 2 or 3 waiting so I did them
Powered down my machine, waited 30 seconds and powered back up from cold. Just to make sure I then did another SFC /scannow which came back clear. Game still won't launch.
I had task manager open whilst launching the game. Memory and CPU usage didn't get get anywhere close to being maxed. Infact, memory barely hit 20% of its capacity.

Okay, Im missing a lot of Exotic weapons from my inventory. Can I please Get My [censored] BACK!!!!!!
