Sounds like you aren't doing something correctly, to install Korax Arena, you have to unzip the file you downloaded somewhere to your hard drive, respecting the directory structure it has, once that's done, you copy your doom, doom2, heretic or hexen WAD files to the directory where the launcher executable is, then you simply run the game after setting it up, it should run fine <!-- s:) --><img src="{SMILIES_PATH}/orc2.gif" alt=":)" title="Smile" /><!-- s:) -->. Hope this helps you out <!-- s:D --><img src="{SMILIES_PATH}/orc6.gif" alt=":D" title="Very Happy" /><!-- s:D -->.
