New thing, while re-installing, it seems I need...

sound/magic/ice_powerup.wav
sound/player/breate_slow1a.wav
thornlands.wad

The files were broken.

Sounds like the game didn't like resizing the screen while still playing. If restarting fixed it, then don't worry about it.

Half-Life auto restarts when changing the screensize. o_o

Oh, and new problem occured when re-installing... files were corrupted in the zip.
