I found problem now 

but cannot fix

 

 

Step of problem is 

example

 

1. folder old ragnarok name   folder "work1" 

 

2. and i copy file in folder work1 build new server

example folder name work2

it can run fine , without error 

but something not connect and cannot login to server

 

3.but if i copy file from work2 to old folder work1

it can run fine !!

and everything ok! play fine! 

(just need to use old folder )

 

4.and If I copy file from folder work1 to another new folder 

it will same number 2 (cannot connect if change folder)

 

 

That mean everything will run fine if i move to older folder.

 

How to fix it ?

make sure everything is `not in use/close` before renaming the folder,
Make sure you copied it completely, and check for viruses on your pc.

you should search things like this in google, instead of asking here.
