This works for D-REX. I'm not responsible if you harm anything, but it's basically the same thing.
What I did:
I was already on REX.
Uninstall Current Spoof
Convert to DEX
Update to D-REX
Install Spoof
Turn on Rebug Mode
Turn on Cobra/Webman
Install Spoof.
I was able to sign in and play games online after. Hope this helps anyone wanting to be on DEX again.
