well. my pattern is this.
1. i open XK trainer. run as admin coz im using 7 . as you can see on DN folder. there are change if you open XK Trainer.
2. Start DN.
3. Just Put back the original Sddyn01.dll on GPK folder and the . GPKitClt.dll on DN folder.
NOTE: You must do number 2 & 3 . at the same time. Click start DN at the same time Put back the original files before the DN window appear. you need to be fast. i try it many times. sometimes work sometimes not.
