@dragonwing: I had the same prob as u, but now I knew how to fix it.
You miss one file hotuk.ini for Jpclient_A. Now all u have to do is download the whole server file again:
http://www.********.com/upload/files...er%20Files.rar
(change ******** in the link above to "mir heros" NO SPACES)
After extracting, u copy both files hotuk.ini & Jpclient_A.exe in the folder AdminClient (in the folder extracted) and paste them in the folder of EPT client u installed. Then it should be alright for u to run Jpclient_A without facing GameGuard Error :)
