@ Threadstarter:
I would suggest you to use the AutoMacroRecorder. This helps you to remove the problem you have with that trial-version:

Scroll down until the post from "StickyIcky" and download what he posted. Then just copy the files into AMR-folder and TADA!!! your AMR (btw AMR is the shortcut for AutoMacroRecorder) is pro version. Also I'd suggest you to put the screen resolution on 1024x768.
After that you should start your KalOnline in window-mode (open your KalOnline-folder, open "system" with editor and change "MODE_WINDOW=0" into "MODE_WINDOW=1". Now it should work.
