I was finally able to fix the gfx acceleration of my PC (which I realized I myself had screwed up some time ago) and now both OpenGL and D3D work <!-- s:D --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt=":D" title="Very Happy" /><!-- s:D -->
I was also able to patch my hexen.wad, I don't know what was wrong though.
This mod rocks <!-- s:D --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt=":D" title="Very Happy" /><!-- s:D -->
Aside from that, I'm getting ocasional freezes in OpenGL mode and even more ocasional in D3D. Also, with the mage, in nightmare level Doomsday crashes when I cross the portal into the wastelands (from the shadow wood).
Anyway, nice work dudes <!-- s8) --><img src="{SMILIES_PATH}/icon_cool.gif" alt="8)" title="Cool" /><!-- s8) -->
