Neuz.exe has stopped working

I just came back again from a very long hiatus and I repatched my Flyff using Administrator privileges. But it doesn't seem to work. I also deleted Neuz.exe in case it would work, but nothing good came out. Any help on this would be appreciated.

looks like you are really an old player.. have you tried downloading the newest client?

Yep. I AM REALLY AN OLD TIMER. I just went hiatus because of my thesis and I couldn't multi-task gaming and thesis. And, it looks like that will be the only way to make. Though it appears that I can only reach the character selection and it stops there.
