NL loader not working

I start the loader, it opens steam and gets into game but after that I got an error " An internal error occured, please restart loader" Error [54] , I restart loader an same problem, the game is runing fine but no ingame NL loader and can’t use the cheat.
Can someone please tell me what can I do, or if it’s a NL server problem and I should just wait to get back on…
Thanks, have a good day.

I have the same exact problem if they get back at you respond to me please ty
