Have you tried downloading the recent released 1.0.1 patch? I suspect that could be the problem, I'll share the download link here: [url:3j0o2mc9]http://downloads.sourceforge.net/Korax/ka_patch_1_0_1.zip
EDIT: Forgot to say this too, make sure that the launcher has marked the "create debug file" check box, then run the game, when it crashes it will have made some output in a debug.txt file inside the 'basev' folder, please post the contents of it here, so we can review what's wrong, thanks for reporting the problem! Hope this can be useful for you <!-- s:) --><img src="{SMILIES_PATH}/orc2.gif" alt=":)" title="Smile" /><!-- s:) --> .
