Basically, I've been having the same issue that has been described in this thread since I got banned (and unbanned a day later) last fall.
Upon starting Recursion, I get the message 'Failed to load the following plugins: RTPluginPS2.dll' and the client itself stays blank (the menu on top is still showing though).
Achievements, kill counter and statistics tabs are not working, the crosshair overlay mod is fine.
I reinstalled several times but it didn't work. Just reinstalling the Planetside mod itself didn't help either. I also tried reinstalling Recursion on a new account that wasn't tied to any characters on the Daybreak account that received the ban, didn't fix it.
As said, the issue started when I got unbanned and has persisted since then, so I figured it could have something to do with it.

If you have any idea on how to fix this, please let me know.
Thanks
