How Do I Get The Wynncraft Client To Work?

There is this thing called the wynncraft client its unoffical but It comes with a couple of useful mods and I've seen it used in videos if you don't know what it is then search it up and you will see. Anyway, when I join the server it has a big message taking up the entire screen about forge involving the modpack and it makes it impossible to play.
If anyone knows any solutions to this problem that would be great! (Yes I've searched it up and found no solutions but if anyone knows any please tell me.)

 

Is it Wynn expansion or Wynn enhanced?

 

It is Wynn Enchanced

 

Possible Solutions:
1. Did you use Forge?
If you used forge, you need to install Twitch or use a Curse account. Search up "curse install" or something like that and it will give you tons of options.
2. Did you use Curse/Twitch?
If you did use Curse/Twitch, then you may need help. Theres a nice thread about it here.
3. Still doesn't work?
Try to find options online. If that still doesn't work, try to contact the guy in charge of Wynn Enhanced.
4. If all else still fails
It is completely fine not to use the Wynn Enhanced. If there is no other option but not to use it, that is completely fine.
