As far as I've checked , there's nothing to do with negative stats or too much stats .
This is either you tried to wear something customized that is making you DC ( If you're dcing because of normal NX , it'll be because of your files as normal players don't DC anyways ) .
There's nothing I can do to help your character anymore , unless you recreate a character . To save yourself from trouble , wear something simple . A normal NX shirt / pants / shoes / hat and face acc will do , or even better just get a full wizet set.
