You saw somewhere download link to 2018-11-14dRagexeRE? Here is not, because all clients unchanged and downloaded as is from official server or mirrors.
Ragexe not works because you doing something wrong. You can use old nemo, missing recommended patches, not updated game guard dll, not using hercules (for rathena i cant do any support, not sure how it works). About rathena i can say only versions where client 100% not works.
Issue can be in anything of this. You can saw herc discord, not long ago some one configured client too, and forgot some must have steps. Also basic info you can see in herc forum here http://herc.ws/board/topic/15523-another-nemo-patcher-fork/. See my comments about versions.
