OK heres the step:
1) Open RF_online.bin using Hex Editor
2) Press CTRL+F and find the word EHSvc.dll (you need to find this line
HACKSHEILD\EHSvc.dll)
3) Rename the line HACKSHEILD\EHSvc.dll to botsnhacks\psapi.dll and
SAVE
4) Go to your RF Directory and make another copy of your HACKSHEILD folder (including contents) and named it to botsnhacks. (You can use any other folder name not more than 10 characters the same as STEP#3)
5) Run the game.
Note: After Exiting RF Online you will always receive and RF_online.bin error just ignore it
Have fun
