Greetings!

Hopefully today all of you are blessed.

In this occasion I would like to give a small hint if your Campus Ragnarok window does not showing up after you click the .exe

STEPS:

1. Don't panic! It is a simple thing even a baby can handle. 
2. Go to your Campus Ragnarok folder, and find a file called OpenSetup.exe

3. Choose your preferable resolution, for me, I love to choose 1366x768x32 

4. Click APPLY, and run your Campus RO Patcher then START!

I think it can solve your problem if campus ro window is stuck.

Good Luck!
